I didn't say multi threaded.

ThreadLocal gives access to the cached object of the current thread.
I'm doing an assumption here that appengine/j is implemented with thread per
incoming request.

What I would like to know is if these threads are recycled (in which case
ThreadLocal is a good approach) or not.

Thanks,
Maxim.
