How to repeat:
------------------
I have to make educated guess here, as no time for a perfect testcase.
Hangs within about 5 seconds on my testbed.
If you need exact testcase, let me know and I'll try produce it.
Start server with binlogging and run two threads that do some random XA, start transaction, commit, DML, and reset master.
