Interesting thread on the removal of LinuxThreads - I myself have been playing with NPTL only systems for quite some time (well over a year now) - in all my time working with them, I only personally found one thing that broke with NPTL libs - and it was a compile-time bug, not a run-time bug - that being the compilation of a UML (User Mode Linux) kernel. Now, mind you, I have not tried to do so in quite some time, but it used to be that when compiling a UML kernel on an NPTL-only system (NPTL libpthread in /lib, no /lib/tls), the compile would fail. However, a kernel compiled on an older LT system, and the binary transferred over to an NPTL system, would work perfectly. Just pointing out another place where this may pose a problem.
