Just as an aside, I seem to remember POSIX making a distinction between
'global' signals and 'per-thread' signals. Something about a signal that
cannot be handled by a thread is queued globally and then processed by
the first thread that can take it, or something like that.
The current code unconditionally (tries to) queue to the first lwp; the next step will queue it on the first lwp that doesn't mask the signal, and failing that, globally. Though again, that's a next-step :).
This would imply that we need to have a two-level signal delivery architecture (lwp layer and process layer).
I guess so too. Simon already has some thoughts about is, we talked this afternoon (while I was reviewing the patch).
