From: John Harrison <John.C.Harrison@xxxxxxxxx>
A hang situation has been observed where the only requests on the
context were either completed or not yet started according to the
breaadcrumbs. However, the register state claimed a batch was (maybe)
in progress. So, allow capture of the pending request on the grounds
that this might be better than nothing.
