nathanw 9639eeaf54 Adapt to pt_trapuc: change STACK_SWITCH to check for a value in pt_trapuc ... and use it preferentially to a value in pt_uc, clearing it once on the new stack. Move stores into pt_uc back to before the stack switch; storing after the stack switch opened a one-instruction race condition where an upcall that had just started a chain could be preempted again, and would bomb when restarted due to its pt_uc not yet having been updated. Now that pt_trapuc is what the upcall code writes to, it is safe to store to pt_uc before switching stacks. Remove obsolete pt_sleepuc code.		2003-06-26 01:45:31 +00:00
