for a ResourcePolicy. These two features will also need a related

fix isn't the most elegant thing in the universe, but it's simple
and it'll do.

we need to move the "continous/non-continous" code snippet out of ConcreteSimulation
and into TextualSimulation/the GUI Simulation. In fact, ConcreteSimulation
is just a state machine that performs a single step and then puts itself
either in paused state (if the Simulation hasn't finished) or into stopped state
(if it finished)

with a *factor* of ~640x480. That means ~64*48*10^6*3 bytes = a ~1.1 Gb RAM pixmap.
The problem didn't show in versions of cairo >= 1.2 because it automagically
clips (yeah, cairo programmers *are* smart :-))
It is temporary fixed for the moment, will be made better asap.

mutexes and set the value when needed (maybe we can improve this?)

that the size of the history was the coordinate of the instant
to add.
- Corrected a bug in step forward, which was incorrectly assuming
that all processes started at instant 0.
- Added a wizard to show a bug in step forward, which thinks that
the simulation is terminated while it isn't since some processes
are still future.
- Commented some unused code in step forward (extendThread()).
- Still to extract methods from Extender and provide them to
step forward in a more suitable (static) way.

at all. Compiles and runs, but the output is not
correct. Anyway, now it is just a matter of logics :P
- Corrected some minor bugs in step forward.
- Step forward is now rather messy, but still better than
four hours ago.. altough this can be hard to believe.
- Added some wizards that help finding bugs.
- Rewritten dyn process get_state as it was guilty of
premature optimization :)

copy constructor and by the add_resource and remove_resource methods
found in ConcreteHistory.
- Scheduler now adds the requests in the queue when appropriate, and
removes them when exhausted.
- Still to implement the management of the state of requests depending
on their position in the queue
- Still to implement the way threads block depending on the state of
their requests
- step_forward now reuses some bunch of code taken from the prototype

derived widget
- Add History::set_notify_enabled() for usage by the frontend
(for example, when loading from file, you'll want to call
set_notify_enabled(false) before starting)

their elapsed time
- requests are now behaving nicely, since they are raised at the correct
instant, and terminated at the right instant
- the ready queues are still not ready, tough :(, anyway, now there is
really nothing else to do before them.
- stepforward is looking much more uglier (if possible).

when that thread had just been given the cpu.
fixed a bug involving text-simulation displaying the wrong timestamp for
each snaphot. Now the first snapshot printed is correctly tagged "-1".
added (for the sake of lazyness) a method to readyqueue letting anyone
delete the first element on the queue. Not having this would imply
rebuilding the whole queue each time a thread was selected to run.
Small commits avoid complex mergings.

the step went okay or otherwise if the simulation ended
- Fix simulation states in concrete_simulation.cc
- Manage end of input (now CTRL+D exits the program, and
you can redirect a file in input knowing that at EOF
sgpemv2 will terminate)
- Fix a bug in Scheduler that didn't add the newly created
environment to History when the simulation ended, thus leading
both to a memory leak and an inconsistency in representing
the simulation
