As a heads-up, I'm leaning towards stripping out the vdso (linux-gate) support at the dynamic linker level entirely, and instead using Nik's original design for vdso-assisted clock_gettime which can work with static linking too. This cuts out some complexity and code duplication in the dynamic linker (at the expense of duplicating the same code elsewhere for use outside the dynamic linker), but the real benefit is that we don't have to worry about the kernel devs doing something stupid and polluting the userspace symbol namespace (and potentially redirecting functions to do the wrong thing) if they add stuff to the vdso that doesn't belong there. If anyone's against these changes or wants to discuss them more, please reply in this thread in the next day or so.. Rich
