everything is fine now with the fix...
Running with T < 21s causes consistent failures in the test (fails on
first test run). Running with T=21 makes the test succeed consistently
(i.e. 4 times in a row successful). So it appears to be a starvation
issue.

This testcase only failed (prior to fixing the bug) when a large number of
threads was used to acquire and release locks. Do you hit a deadlock or is
it starvation? Perhaps we need to increase the timeout. If you do hit a
deadlock, it should not matter what the timeout is. We can even give it 1
hour if needed.

The PageAccessSynchronizerTest#ReleaseUnderLoad() test fails when

Java 6:
java version "1.6.0_65"
Java(TM) SE Runtime Environment (build 1.6.0_65-b14-462-11M4609)
Java HotSpot(TM) 64-Bit Server VM (build 20.65-b04-462, mixed mode)
Unfortunately this breaks the release process considerably. Some
testing showed that for N=20 (I guess the number of threads is the
number of concurrent simulated requests) makes the tests run
smoothly.
N=25 intermittently fails the test with 1-2 errors, N=100 shows 5, 56
or more errors.
Is testing with N=100 necessary or are we then just testing the
locking/unlocking speed of the JVM?

Of course it works running java 7, but I'd rather not use that to cut
our release.
