The following test has started timing out in the jdk/jdk CI:

compiler/loopopts/TestOverunrolling.java

so far on the MacOS X machines.

Here's a snippet of the log file:

The test is using the default timeout value of 120 seconds/2 minutes
and this task uses a default timeout factor of 10 so the total timeout
value is 20 minutes.

Notice that the test passed while the JTREG timeout handler
was doing its work.

Taking a quick look at CI results for this test, I see passes for
this test in < 1 minute so I'm not sure why this test sometimes
takes a long time.
