mq: avoid a silly conversion from binary nodeid to hex We generally deal with binary nodeids in code. In this case the hex nodeid was passed to strip.checksubstate() where it was passed to repo.__getitem__, which of course accepts a binary nodeid.

# Dummy extension that adds a delay after acquiring a lock.
#
# This extension can be used to test race conditions between lock acquisition.
