Not so "easy" for Windows.

I think I'll simply #ifndef WINDOWS my addition.
Maybe the leak does not exist on Windows? but if it does, the
situation won't change by doing nothing on Windows.

If there is strong objection, I'll need some help to add a
pthread_detach() wrapper in windows EAL.
From my quick read at the API, I'd say I need to find the current
thread handle (via OpenThread) then CloseHandle it.
But does it work from "pthread_self()" ?


Since a new API thread is in preparation, the "thread detaching" from
the pthread API is something to consider.
I could not find it in Narcissa series.
