Looking a little farther down the code, I see that the lock is
released not to far below where the issue is happening.  By moving the
release up the issue disappeared.  I couldn't see any section of code
that directly needed the lock, and those that did were locking on
their own anyway.

Hopefully the new patch is close, if not acceptable to be merged.
This issue seems to be a block on 1.8 for those using Realtime
configuration for the dialplan.
