Hello, Justin.
Thanks for your attention.
After some investigation, I think I have found the problem. It is
caused by XLOG_RUNNING_XACTS at an undetermined moment (some test
parts rely on it).
Now test waits for XLOG_RUNNING_XACTS to happen (maximum is 15s) and
proceed forward.
I'll move entry back to "Ready for Committer" once it passes tests.
Best regards,
Michail.
