Review request for qpid, Chug Rolke, Cliff Jansen, Kim van der Riet, and Steve Huston.

Bugs: QPID-5531

Repository: qpid


If a rogue external Transaction Manager forgets to commit/rollback a prepared DTX, Tpl store
keeps an orphaned enqueue record. To prevent it, every DTX transaction should have a default
timeout after that the broker automatically aborts the transaction.

QPID-5531 adds broker option dtx-default-timeout for that.

My concerns for review:
- is 3600 seconds as default value proper? Isn't it too high?
- ms-sql and/or ms-clfs store part of the patch (recoverTransaction method) has not been even
