Looks more like you should be getting chunk underlocked. When you do a
MemPtrUnlock on a pointer that points to a locked handle, it actually
unlocks the handle. See the docs. So you should not be able to unlock the
handle afterwards. Also, using DmQueryRecord does not mark the record as
busy (it is read-only), so there is no need to DmReleaseRecord (in other
words you should not do this).
