#define DEBUG_SIGNALS
/* KNOWN BUGS 24 May 02:
- A signal is not masked in its own handler. Neither are the
signals in the signal's blocking mask.
- There is only one pending set for the entire process, whereas
POSIX seems to require each thread have its own pending set.
This means that a signal can only be pending for one thread at
a time.
- The following causes an infinite loop: start Hugs, Feb 2001
version, and do Control-C at the prompt. There is an infinite
series of sigints delivered (to the client); but also seemingly
to valgrind, which is very strange. I don't know why.
Probably a lot more bugs which I haven't discovered yet.
