I'm about to commit a fix to this effect. The private API:

LDAP_F( void *)
ldap_pvt_thread_pool_context LDAP_P((
        ldap_pvt_thread_pool_t *pool ));

will return the current thread's contex, given a thread pool.

In order to implement this I needed to extend the thread abstraction
to support querying the identity of the current thread, as well as
keeping a list of active threads in the thread pool.

Finally, I also added support for the Sun ONE DS 5.x mutex and
condition API, which provides plugins targeted at both directory
servers with a portable synchronization API.

Interesting idea, I hadn't thought of that! Not spawning an extra
thread is probably to be preferred, though.
