select returns -1 on error, which is never checked. This makes the function unresponsive to OS signals (EINTR), among other things.

i guess a patch/PR would be helpful.

Any reason why a simple if(result==SIG_ERR) return 0; didnt made it in yet, or shall i do that one? ^^

SIG_ERR isn't the check.

if (result == -1 && errno == EINTR) ...
