tests: Slow down generator tests to work around race condition

5ms resolution is too fine for reliable tests.  Increase delays by a
factor of 10 to improve the chances that the desired path will win the
race.

Ideally the test would be rewritten to remove the races entirely, but
I'll leave that as a future exercise.
