Final for World Series: Python vs Ruby
3023 [thucdat@ho m] Perl and Tcl seem to eliminate themselves from the play-off round.
3024 [excalibor@de] I'd take that notice with many grains of salt... I've looked for the original USENet post this was supposed to come from and deja.com found nothing...

3035 [decoux@mo lo] I need, for an extension, to use rb_thread_wait_for() and

Thread priorities
3059 [Dave@th ma e] c1 = 0
3083 [matz@ne la .] No, there was a bug.  But when the bug is fixed this program hangs,

3089 [Dave@th ma e] That's great. Thanks.

Is divmod dangerous?
