Yes, there's a bigger timeout for acceptance tests, but iotests doesn't
have the same just yet.

In general, it helps for most of the python library methods to time out
by default to prevent hangs in the various test suites.

So, anticipating that iotest callers will probably want to use wait()
sooner or later, I just went ahead and made the change primarily for
consistency again.
