Okay. I'll need to figure out how to recompile glibc without NPTL then... FYI, it looks like Xen has found a way around this problem. Basically, they dynamically rewrite the NPTL instructions, with an overhead supposedly near zero. I don't know if something like this is possible with UML, but it sure would eliminate a whole class of questions on this list. And it would be an even bigger help for people with newer architectures where NPTL support is simply assumed.
