Does using the GNU pth (via pthreads) also require any rebuild
of the Berkeley DB2 backend against the new library ? I didn't
think so, but just to make sure...
Also, what kind of performance difference can one expect to see
with the non-premptive threads ? Is it likely to be much worse ?
Thanks, Vinod.

The warnings apply to all versions of OpenLDAP 1.x.

If you want stability, use a non-preemptive threading system.

As in GNU Pth, yes. OpenLDAP 1.2.10 supports Pth native
interface (prior versions used its pthreads interface).

Your mileage will vary.
