I might have spoken too soon: JTReg seems to collect stdout and stderr and print them out at once at the end of each (JTReg) test. In this case it doesn't make much sense to print out the output of each test as soon as it finishes (it would be better to collect them and print them in order at the end). @chhagedorn, is there possibly a way to make JTReg print the output "on-the-fly" that you are aware of?
