It's only happened three times on the linux build machine and it checks
for changes every hour.  It's never happened on the windows build
machine and I've never been able to reproduce it on my own machine.  The
only clue is that the last message in the log before it hangs:

[junit] java.lang.OutOfMemoryError: Failed to fork OS thread
[junit] 	at java.lang.Thread.startImpl(Native Method)
[junit] 	at java.lang.Thread.start(Thread.java:1015)
[junit] 	at tests.api.java.lang.ThreadGroupTest.asyncBuildRandomTreeUnder(ThreadGroupTest.java:1292)
[junit] 	at tests.api.java.lang.ThreadGroupTest.access$000(ThreadGroupTest.java:20)
[junit] 	at tests.api.java.lang.ThreadGroupTest$16.run(ThreadGroupTest.java:1289)

The ThreadGroupTest never completes.  (This was building r410365 in 
case the line numbers don't make sense any more.)

I've not really had a look at what might be causing it yet.
