Well, it turns out that your suggestion was correct.
I did some more searching and found another similar suggestion, so I
gave it a whirl, and it works.
Now, my problem is that Jeremy Allison thinks that it is a fugly hack.
This means that I will probably have big problems getting a patch for
this into Samba.
I don't understand why JA thinks this is a hack. Their current
method doesn't work, or at least isn't portable. I've tried this
on Solaris 10, and it works just as it does in FreeBSD. Test
program included after signature.
$ ./test_sigprocmask
Sending signal 16
Got signal 16, blocked: true
Blocking signal 16 using method 0
Handled signal 16, blocked: false

Yeah, people think that signal handler is normal code, this is a
misunderstanding, in fact, it really works like an interrupt service
routine.
