Should ALL threads be awakened, or is it enough if ONE thread awakens to deliver the thread.
For right now it's mostly important that single threaded processs act as they used to. We can always change how multithreaded processes work.
POSIX makes no guarantees for threads delivery of signals.
Specifically, signals are not thread-things, they are process things, and there are seperate threads-things for sending the moral equivalents (e.g. pthread_kill) to threads on an individual basis, but the system is not expected to make a distinction on signal delivery as to what theread is running, nor are there expected to be per thread masking, etc..
Garrett would probably be the right person to ask; he's a much better POSIX lawyer.
This is really the problem I tried to explain earlier when it came to the disabling on SIG_POLL on a per descriptor basis.
