#989: High CPU usage when calling signal handler multiple times

Comment(by sjamaan):
Oddly enough, if I throw out the HAVE_SIGACTION from Makefile.bsd, make
spotless and rebuild, it still fails the same way (on master). It seems
to be related to the reworking of the signal handling itself.
gdb seems to point to an infinite loop in the GC, but that's rather
difficult to understand given the setjmp/longjmp stuff. ktrace shows that
it keeps setting and resetting a signal mask.
