Yes.  However, I wasn't suggesting using or copying code from the
free dce package.  You can merely examine it and decide whether
implementing thread cancellation in such a way is something we want
in APR.  Then, you write your own implementation.

Furthermore, I would like to compare the Free DCE threads implementation
with the DCE/RPC threads implementation.  Then pick the best design
decisions from both.
