Previously, the test could fail on slow machines because the
child process was still in the process of starting up after
one second, and not yet idle.
To resolve this:
- Wait for a message from the child process indicating that it
had started.
- Wait some time after that, but make it platform-dependent to
account for timing differences.
- Remove the timer in the child process.
