I *think* it was picked up from OpenBSD, where I *suspect* it was done because it's unsafe to do very much in a signal handler and the concern was that longjmping out of a signal handler could leave some part of the application or libraries in an inconsistent state. (This is *definitely* a problem on Mac OS X, for example, where Ethereal, which still does the alarm()/longjmp stuff, can sometimes *crash* if you longjmp out of a host name lookup.) > Latest tcpdump is rather slow at exiting from a SIGINT now and > even more so with the new pcap_break_loop(). "pcap_break_loop()" shouldn't make things worse; I'll look at that. - This is the TCPDUMP workers list.
