The keys are known at linking time when a) their context is module-local and b) their TLS storage can be appended to main's TLS area (and that can only happen during initial linking, of course). BTW, another advantage of TLS over getspecific /wrt task-self is that it overcomes its laziness: its now cheap and easy to set self in the thread trampoline. Philippe, could it be that vrtx's sc_tinquiry implementation is broken? I only find the corresponding pthread_setspecific in the lib constructor. That pattern totally disagrees with native and vxworks.
