Another data point, I have a simple test program that has the same
result (as my kids would say, "java goes 'trip, thud'") just by using
SecureRandom (who fires of a whole load of threads). You have to
run it about 50 times, but eventually it will dump core. I made
it a Swing app to get the additional AWT and friends threads to help
speed up the "trip, thud" process.
The problem existed in p5 as well (actually, I think it happens less
often in p6, but I don't have any hard data to back that up).
Unfortunately, I have not had time to debug it farther.
