but I have to check the impact on simulation speed (e.g. does moving
the mouse increase the speed of simulation? that would be bad!). To
fix it properly, the glib event loop should be hacked up to run the
event loop together with Smalltalk code:
* Place the main loop at high priority and make it do something
like this: 1) use g_main_context_set_poll_func and in the poll function
set up SIGIO notification for the file descriptors, call
g_main_context_pending to get this poll function called; 2) wait on a
semaphore to be triggered by the SIGIO notifications; 3) revert to the
default poll function and call g_main_context_iteration in non-blocking
mode.
* Besides this, in sysdep/win32/events.c use
MsgWaitForSingleObjects instead of WaitForSingleObject
