As I expected, Russell stated that patch 20101219-blind_deadlock.diff will
not be merged.  I wasn't very happy with the way it avoided the issue
anyway.

This issue also disappears when using static extension configuration using
the same data as the Realtime configuration.  As far as I can tell, the
current build tests for blind transfers do not use any Realtime
configuration which would expose the issue.
