Do the default signal handlers for Linux behave as if they were installed with
SA_RESTART, or not? (I tried querying 'em with sigaction but the defaults
all have sa_flags 0.)
I remember years ago hitting a bug where ctrl-z followed by fg would cause
pipelined processes to drop data, and would like to avoid that without having
to wrap every darn syscall and check for -EINTR. I _think_ that I just have
to feed SA_RESTART to the signals I register handlers for myself, but I'd
like to confirm that.
