Log message:
Make sigwait() work correctly. In particular, it'll work when the
signal is already pending in the calling thread or the main thread
and there's no longer a race condition where the signal could be
diverted but sigwait() would still block. There were some off-by-one
errors too.
(The checking of the main thread's pending list is just until a
pending list for the process can be added to struct process. For
now, such signals end up as pending on the main thread.)
