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.

v2: Reword 'not started' warning message (Tvrtko)
