If the issue is just that select() doesn't get interrupted and we don't
care about a couple of syscalls, would it not be better to simply use
sigaction to turn on SA_RESTART just prior to the select() and turn it
off just after. Or are these systems so broken that select() won't be
interrupted, even if the signal handler is explicitly configured to do
so?

Have a nice day,
