It doesn't do a lot at all. It sets SIGPIPE tp SIG_IGN, and SIGWINCH to a
signal handler. At least on Linux, this happens with SA_RESTART set by
default (but I don't know if we do it by default, too).
However, we don't resize the terminal anyway, so this signal should not be
raised, right?
The only other signal related thing it does is, while updating the process
bar, it blocks SIGWINCH temporarily with sigprocmask. Can it be that this
block/unblock can confuse select?
Do we have SA_RESTART by default?
Can I see which signal interrupted select()? Where would I set my
breakpoint?
Thanks,
Marcus
