contrib: open a hole in the open().read() ban for open().close()
It turns out open().close() is both fine and something we occasionally
do to verify something can be written. The few cases in the codebase
were getting missed due to a regular expression bug (which I discussed
in my previous change), but since I'm about to fix the bug, I need to
fix the patterns.

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