Sorry this has taken so long to review.

So this will start a new local server thread for each registration,
which doesn't sound like an improvement.  Possible other options
include allocating a larger memory block which could be shared by a
number of registrations or using the running object table.

Also, please try to update the existing comments when changing the
implementation, this patch left several comments that were no longer
correct.

Huw.
