As I tried to explain below, this option allows the user
to hit Alt F1/F2 to switch between virtual consoles,
graphics mode and text consoles.

> Now, I'm calling GrGetNextEventTimeout() with
a value of 1000 ms BUT THERE APPEARS TO BE ANOTHER TIMER WITH A TIMEOUT
OF BETWEEN 49 OR 50 ms (and sometimes 1 ms and sometimes 7 ms and
sometimes others) THAT CONSISTENTLY TRUMPS MY 1000 ms TIMEOUT TIMER.
Linux's select() function is then called with this much shorter timeout
and, even though there's no event, a GR_EVENT_TYPE_TIMEOUT event is not
generated.
Hmmm... Make sure VTSWITCH=N, since the
drivers/vtswitch.c code calls GdAddTimer to deal
with changing consoles when drawing. You might
also grep for GdAddTimer and find any other
code that might create a timer.
For debugging, perhaps add some printf() code in
the addtimer routine so you'll know what timers are
being created.
Keep me posted, we'll get this fixed

Greg
