fvdl 8655b27bf5 SA fixes from Stephan Uphoff. Quoting him: 
The patch below (hopefully) improves some signaling problems
found by Nathan.

It also contains some cleanup of the sa_upcall_userret() function
removing any sleep calls using PCATCH.

Unblocked threads now only use an upcall stack after they
acquire the virtual CPU.
This prevents unblocked threads from stealing all available
upcall stacks.


Tested by Nick Hudson.
