Just making sure.
I have a hard time figuring out what is going wrong, and especially
why it is going wrong on windows.
Some discussion with Aaron lead us to a problem that shows
up with threading:
Create a pool A.
Create a thread
- create a subpool B of A
- launch the thread.
Destroy pool A
- implicitly destroys pool B
Thread exits
- Destroy pool B
B is being destroyed twice.
To protect against that we either need thread cancellation, and
register a cleanup with pool B that will cancel the thread if
the pool is destroyed. Or, we need other means of protection
against double destruction (refcounting of pool users(threads)
comes to mind).
