The threads library in -current (hopefully) fixes these problems. I am hesitent to MFC to -stable without further testing in -stable. I have had two reports of problems in -current that I cannot reproduce. Another problem that I found was with languages (GNAT) that use builtin setjmp/longjmp in conjunction with pthread_kill() to implement asynchronous transfers of control. I'm currently trying to fix this but I won't be done before Nov 1. Latest diffs to -stable are at: http://people.freebsd.org/~deischen/libc_r.diffs-stable Feedback from those with big mysql databases is appreciated. -- Dan Eischen To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
