      Description

      Very occasionally (about 2% of runs), when running ha_tests.py in a long loop one of the brokers deadlocks with the attached stack trace. The problem is a call to TimerTask::cancel with the LinkRegsitry lock held, while another thread is in TimerTask::fire and waiting for the LinkRegistry lock.
