If my SSH session conks out, I'd kind of like it to just kill of the PHP process by default, since I'll try to log back in and start over. I guess that's a reasonable expectation to keep it that way. I realize, of course, that a Un*x guru like you is going to know some fancy dancy way to re-attach your new tty/shell thingie to the still-running PHP process when you log back in, but your average developer, not so much. :-) I probably have unknowingly relied on this behaviour more times than I can count, personally. I could probably get used to it if it changed though. Actually, for a long-running php script, or a shaky connection, I usually re-direct to a log file and background it, but even that is more than some "Devs" are going to "get". -- Some people ask for gifts here.
