ok reverted back to old scheduling for now....
Revision 1.18 2004/09/06 22:01:28 reddawg
Created functions sched_addDelTask and sched_getDelTask so we can lock the delete task list to prevent corruption of pointers.... a very random case but possible none the less

sched: we now yeild almost propper
syscall: it still uses ebx,ecx,edx
Boys don't cry
Revision 1.15 2004/08/26 22:51:18 reddawg
