---------------------------------------------
Hey [~dima5rr]
This test assumes only one thread per instance in order to hook into Streams
and and force a commit or a crash, for example. I would not expect it to pass
if you change the number of threads.
It could be extended to work with/test a multithreaded upgrade if you'd be
interested in submitting a PR, though :)
