Here's an interesting read on the subject:

For those of you not familiar with the language of standardization, this is an official letter from the C committee to the C++ committee saying: "Thank you for removing cancellation. Now we want you to promise that you will not even discuss bringing it back."
I just spotted that in the mailing. Ouch. I know we removed cancellation so we could make progress on other stuff, but I really think we ought to bring it back. One of the key things people have said to me when I have mentioned that we're standardizing a thread library for C++ is "does that include cancellation?" Everyone I've spoken to about it has been very glad the answer was "yes." I've added cancellation to the boost thread library (though currently this_thread::cancellation_point is the only cancellation point on pthreads --- something I intend to fix), and I don't intend to remove it.
