Can you expand on that? In particular, I would be grateful if you could clarify "cancellation". Cancellation in pthreads is requesting the termination of a thread, where I neither see how that is important in the Hurd, nor what is missing for that in the current implementation. So I guess you are referring to the interruptable RPCs. Either we keep the current implementation, but put it on top of pthreads rather than cthreads, or we change the Hurd to use the pthread infrastructure for that (I guess that means using pthread_cleanup_* in the relevant places and using the terminating pthread_cancel, rather than using the hurd_condition_wait semantics, where a non-zero return value indicates cancellation).
