Under load sometimes the 1 millisecond timeouts are not run before
a 1 second sleep finishes, or `echo foo` is not run before a 1
second timeoutt. Increase the long sleeps and timeouts to 10 seconds.
This doesn't affect normal test runtime as the command should timeout
after 1 millisecond.

determine which log statements came before the timeout and the
on_timeout command.

Use a concurrency-safe writer in runWithTimeout to avoid data races
