That gets you the os thread, aka a pthread_t.

It doesn't get you the apr_pool_t that APR has associated with its own 
apr_thread_t that APR created when it made the thread.

I think the only way to do this is to extend the request rec, or 
significantly change the APR API around threads and pools, with the 
later being a much more complicated exercise
