I see. I just ran the tests and it seems that 
SemaphoreTest>>testWaitAndWaitTimeoutTogether is the problem. However, I 
do think the test is wrong. You can't really use #wait and 
#waitTimeoutMSecs: together. Deleting the test makes this problem go 
away. Note that you may also consider the fixes here:
