We have done most of the work for pthread_cancel(). The problem is that, by default under the POSIX cancel model, all frameworks have to actively protect themselves against unexpected cancellations (rather than explicitly allowing them). That's easy enough to add to Libc/Libsystem in Darwin, but there are tons of frameworks in Mac OS X that would need to be modified to protect themselves appropriately.

Is there any info of when it will be available?

When we figure out how to allow cancellation in applications that only use the basic frameworks, but block it when using frameworks that aren't aware that cancellation even exists, we will add it in.
