I don't think that he's asking if there's a way to figure out what uses LinuxThreads, he's asking if there's a way to figure out what breaks with NPTL. And the answer to that question is: no, there isn't any way, besides noticing that something dies/behaves erratically/etc. with NPTL but not with LinuxThreads. -- Nicholas Miell <nmiell@xxxxxxxxxxx> -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx http://www.redhat.com/mailman/listinfo/fedora-devel-list
