Not true, more on the contrary: http://www.redhat.com/docs/manuals/enterprise/RHEL-4-Manual/release-notes/as-x86/ "While most threaded applications were not impacted by the introduction of NPTL, applications that relied on those semantics of LinuxThreads that were contrary to the POSIX specification would not operate correctly. As noted at the time of NPTL's introduction, Red Hat recommended that such applications be updated so that they complied with POSIX (and could therefore use NPTL.) While support for LinuxThreads still exists for Red Hat Enterprise Linux 4, this statement serves as advance notice that Red Hat Enterprise Linux 5 will no longer include support for LinuxThreads. Therefore, applications that require LinuxThreads support must be updated before they will be able to work properly on a Red Hat Enterprise Linux 5 system." Johannes
