- updated to 2.01
test waitport argument by running full code-chain, not with partial mocking

The partial mocks cause stuck forks on win32 at times, causing the test to
hang. With the full code chain present the test runs reliably
[INCOMPATIBLE CHANGES]
- Change wait_port() API to take max_wait seconds, and wait exponentially.
Dropped wait_port_retry argument introduced at 1.27.

- Increase the default sleep and retry: 0.01 sec and 1000 times
