Have you tried it with libthr on -CURRENT ? David Xu -----Original Message----- From: owner-freebsd-threads@freebsd.org [mailto:owner-freebsd-threads@freebsd.org]On Behalf Of Mikhail T.

None = of the other threads get enough time because they are all waiting for = the global mutex lock from the main process thread when its their = turn. The main process thread is hoging the global mutex while it's in = its loop. It's not a deadlock, it's just a type of thread scheduling = that doesn't happen on other operating systems. Whether it is a bug or a legal oddity, our threads (CC-ed) people would love to hear about it... = Adding a sleep() or a yield statement in the main thread of the test = allows the test to finish. The fix will be available in ICU 3.4. -mi _______________________________________________ freebsd-threads@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-threads To unsubscribe, send any mail to "freebsd-threads-unsubscribe@freebsd.org"
