I would like to find out if this is the same person I have
reporting this problem from another source, or if this is
a confirmation of a bug I was helping someone else with.

Have you been in contact with Michael Dexter about this

If not then we have at least 2 reports of this unbound
wired memory growth, if so hopefully someone here can
take you further in the debug than we have been able
to get.

Our experience as well.
