(1) This can race with other signals.

(2) This allows SIGWINCH to "erase" a concurrently arriving signal.

I am trying to fix this instead by ignoring signals (poll returning EINTR)
which do *not* set bb_got_signal. (This needs a bit of surgery in hush
to not set it on SIGCHLD).

Please try current git.
