Yes, it must be a racing issue.

It happens much more often in the last test (the one I commented in past 
because nighlty builds was randomly failing). Nightlies and Hudson never 
failed since that change, but it is good to know that this is also 
happening in simpler tests.

I've tried running multiple times the tests on my machine (core duo 2) 
now and I'm not able to reproduce it. I'll try on another box.

Maybe adding a Thread.dumpStack() on assertion failure can give us more 
hints, WDYT?
