I did have remarkable few problems with the AIX 4.3 pthread library (before they started the N to M user to kernel level scheduling thingy). Also the Solaris 8 one user level thread to one kernel LWP thread library in /usr/lib/lwp works remarkably well. The Solaris N to M user to kernel level thread library appears to complex to make it work well at all. -- Jens-Uwe Mager <pgp-mailto:62CFDB25> <jabber:[EMAIL PROTECTED]>
