-# LDAP has a problem with the idea of implicit vs. explicit yields
-# in call conversion threading packages, like the MIT pthreads
-# package.  Rather than resolve this globally, I have marked the
-# threading as "preeemptive", even though it is technically not.
-#
-# This means that the implicit-yield threading is topologically
-# equivalent to preemptive threading.
