Please don't top-post.

Like most other system calls that block "indefinitely", select(2) will
be interrupted by signals.  This is *also* documented in the man page
you didn't read:

     [EINTR]            A signal was delivered before the time limit expired
                        and before any of the selected events occurred.

See sigaction(2) for details on how to modify the way system calls
behave when a signal is delivered.
