output of test execution

Executing 'ninja check-lldb' produced a fail in

However, when I executed the test with './bin/lldb-dotest -p
TestConcurrentSignalWatchBreak.py' the test passed. So, this test sometimes
fail, sometimes pass. I suspect some thread synchronization issue or a
wait/poll problem here.
