Merge pull request from minrk/parallel_wait...

Merge pull request from minrk/parallel_wait improve patience for slow Hub in client tests adds a first step in `_wait_for_idle`, where it waits for all tasks to arrive before waiting for no tasks to be running. On a super slow machine, it was possible for `_wait_for_idle` to return prematurely, before tasks had even started. closes
