Comment (by pulkomandy):
@waddlesplash: if you had read the linked bugreport on homeworld side, you
would have noticed that Philippe Houdoin already tracked where the problem
is. The issue is in Mesa (the legacy version).
It uses a BLock in an unusual way, which worked on BeOS but resulted on
the lock being always held in Haiku (since before I adde dthis check, the
Unlock call would simply have been ignored). In the Mesa code there is a
mention of adding this specifically to get Quake 2 working. So now we have
to find/build a Quake 2 port and make sure it doesn't need this anymore.
Or, we can comment the debugger() call or convert it to an stderr warning.
