I'm confused about what you think that would accomplish.  AFAICS, the
point of BackgroundWorkerHandle is to allow the creator/requestor of
a bgworker to verify whether or not the slot in question is still
"owned" by its request.  This is necessarily not useful to any other
process, since they didn't make the request.

The thought I had in mind upthread was to get rid of logicalrep slots
in favor of expanding the underlying bgworker slot with some additional
fields that would carry whatever extra info we need about a logicalrep
worker.  Such fields could also be repurposed for additional info about
other kinds of bgworkers, when (not if) we find out we need that.
