Seen while working on Tachyon. The tests where running, I hit ctrl-c to cancel. The following traceback happened and then Lousy hung. It didn't seem to be using any CPU time. Traceback (most recent call last): File "/Users/travis/bin/lousy", line 1937, in <module> result = args.func(args) File "/Users/travis/bin/lousy", line 1910, in cmd_run runner.run(tests) File "/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/unittest/runner.py", line 151, in run test(result) File "/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/unittest/suite.py", line 70, in __call__ return self.run(*args, **kwds) File "/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/unittest/suite.py", line 108, in run test(result) File "/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/unittest/case.py", line 391, in __call__ return self.run(*args, **kwds) File "/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/unittest/case.py", line 327, in run testMethod() File "/Users/travis/projects/tachyon/trunk/tests/component/terminal.py", line 544, in test_csiClearLine_default self.assertVtyCharIs(10, i, c) File "/Users/travis/projects/tachyon/trunk/tests/tachyon.py", line 40, in assertVtyCharIs self.syncOutput() File "/Users/travis/projects/tachyon/trunk/tests/tachyon.py", line 105, in syncOutput self.tachyon.flushOutput() File "/Users/travis/projects/lousy/trunk/lousy.py", line 1147, in flushOutput while self.stdout.read() != '': File "/Users/travis/projects/lousy/trunk/lousy.py", line 991, in read ready, _, _ = select.select([self.pipes[self._fileno]], [], [], timeout) KeyboardInterrupt ^C ^C^C^C
