Some general comments on the coding for tests like this:
* It is preferable to avoid sleep in tests to avoid increasing the
minimum amount of time a test takes to run. This helps limit the overall
time it takes the test suite to run.
* If timeouts are used, it is recommend to factor the maximum time
waited with the jtreg timeout scaling factor; I don't recall its exact
name. In other words, many of our tests are run on heavily loaded
systems and the tests take longer than run than on typical laptops and
workstations so jtreg is invoked with an timeout scaling factor.
Individual tests should be sensitive to this scaling factor for any
internal timeout that need to be used.
