May I drop in an innocent (or blaspheming?) question?
Why do we want cancellation? Which kind of cancellation do we want (if at all)?
Cancellation implies a system call, as it is most useful in conjunction with implicit cancellation points such as blocking system calls (read(), say). The one use case that could be implemented in user-space is where the developer explicitely calls pthread_testcancel(), and so could be implemented on top of an alternative API. Not so the first case mentioned above. Regards, Stefan -- ...ich hab' noch einen Koffer in Berlin...
