That's a nice message asserting that it is so, but I don't know of any real
documentation that detached threads are non-cancellable.  In fact, the
documentation of pthread_cancel both on the manpage, as well as in the
POSIX specification make no such restriction on the use of pthread_cancel. 
So I'm puzzled as to where that bare assertion came from.

In fact, we cancel other detached threads in Asterisk with no problem at
all.  So I think you're finding the wrong solution to the stated problem,
and we need to find the real reason this is crashing.  Do you have a
backtrace, perhaps?  I've noted in another place recently that there is a
possible race when a thread is created and destroyed in the same context
switch, although that is probably not happening here.
