. in a pre-emptive OS there should be no freezing;
given the new concurrency model
that includes the use of the graphics processor GPU
to do the system's non-graphics processing,
my current guess is that the freezes happen when
something goes wrong in the GPU,
and the CPU is just waiting forever .
. the CPU needs to have some way of getting control back,
and sending an exception message to
any of the processes that were affected by the hung-up GPU .
. could any of Apple's developers
correct this theory or comment on it ?
