* Fix bug in which worker import counters were treated incorrectly. * Fix bug in which cached functions-to-run were double counted as exports. This also runs the functions-to-run on the driver only after ray.init is called. * Only define reusable variables locally after ray.init has been called. * Remove flaky reference counting tests. It's not clear that these tests make sense. * Make numbuf pip install verbose. * Export cached reusable variables before cached remote functions. * Fix bug causing the worker to hang sometimes. This happens when the worker is trying to run a task, but it hasn't imported enough imports to run the task, so it continually acquires and releases a lock while checking if it has enough imports. However, for some reason, the import thread is waiting to acquire the same lock and never does so (or takes a very long time to do so). By dropping the lock before sleeping, this makes it easier for other threads to acquire the lock. * Acquire locks using 'with' statements. * Fix possible test failure. * Try to start Redis multiple times with different random ports if the original attempt failed. * Fix test in which we redefine a remote function.
