Thread cancelation is difficult to do correctly in a C++ program,
because you want to run all the destructors of stack objects of
the thread being canceled.
Bill Kempf might want to elaborate.

We need a "lock" object that unlocks the mutex in the destructor in all
cases anyway to make the lock exception-safe. There are different
mutex objects so the user can express the features he requires from
a mutex as precisely as possible, thereby allowing efficient implementation.

Typelists are currently being discussed.
