A recent extension to the test runner introduced support for running tests in parallel using multi-threading. Following this, the runner would incorrectly emit the "final report" before all individual test results. In order to emit the "final report" at the end of the output stream, the parent thread would initialize all children and wait for availability of a "log lock" shared by all children. According to the documentation on the "threading" module's Lock object [1]: > When more than one thread is blocked in acquire() waiting for the state > to turn to unlocked, only one thread proceeds when a release() call > resets the state to unlocked; which one of the waiting threads proceeds > is not defined, and may vary across implementations. This means the primitive cannot be used by the parent thread to reliably detect completion of all child threads. Update the parent to maintain a reference for each child thread, and to explicitly wait for every child thread to complete before emitting the final result.
