I started on a patch series to untangle the IPC locking, so
it will be a little more readable, and easier to maintain.

It is a slower approach than Davidlohr's, as in, it will take
a little longer to put a patch series together, but I hope it
will be easier to debug...

I hope to post a first iteration of the series by the middle
of next week.
