On all kernels up to RH9 threads are implemented as separate "lightweight" processes. While this mostly works well enough, it isn't really the way threads are intended to work, there are apparently some "minor" areas in which it doesn't do exactly the right thing. (though for the purposes of a MT program I wrote and maintain at work, it's just fine). Beginning at RH9, they are using the new threading mechanism that properly implements threads as all members of a single process. Therefore, on RH9 MT programs will show in the process table once, and on prior versions there will be one process per thread plus one additional process for a "manager thread". > > Can someone enlighten me. > > Rob Cartier > > > > -- > redhat-list mailing list > unsubscribe mailto:[EMAIL PROTECTED] > https://www.redhat.com/mailman/listinfo/redhat-list -- ------------------------------------------------------------------------------- .---- Fred Smith / ( /__ ,__. __ __ / __ : / / / / /__) / / /__) .+' Home: [EMAIL PROTECTED] / / (__ (___ (__(_ (___ / :__ 781-438-5471 -------------------------------- Jude 1:24,25 --------------------------------- -- redhat-list mailing list unsubscribe mailto:[EMAIL PROTECTED] https://www.redhat.com/mailman/listinfo/redhat-list
