Er, openbsd. pselect() only would be a crash landing for Chris Kuethe.
It's not a problem, though. pselect() is easy to check for; the
autonfiguration in scons took me a whole 3 minutes to write, and
keeping the select() code path adds only a very little complexity.
The work Mike Frysinger and are are doing on cleaning up the
signal handling should reduce that increment.
