i don't know if anyone (other than me) has subscribed to the new flow list yet. my rfc on asynch I/O has been posted there. i feel i should repost it to language but i am not going to yet. in any case if you are interested in threads, event loops, safe signals, coroutines, and asynch I/O and callbacks then subscribe to flow. this brings up the points recently made by various people about autosubscribing (no!) or delayed subscribing etc. here is a new group with no members and no traffic yet and i want to get it moving since we have a deadline! :-) uri -- Uri Guttman --------- [EMAIL PROTECTED] ---------- http://www.sysarch.com SYStems ARCHitecture, Software Engineering, Perl, Internet, UNIX Consulting The Perl Books Page ----------- http://www.sysarch.com/cgi-bin/perl_books The Best Search Engine on the Net ---------- http://www.northernlight.com
