I test at the prompt, not on cygwin, so it is nearly certain that no-one has tested it on cygwin and the but is as old as the code. Another difference is that when testing we invoke as dist\bin\jython, whereas after an install, as just jython, implying a path search by the cygwin shell, finding (I suppose) the script jython first.

Your patch, as I read it, ensures that the OS (which is what subprocess will talk to, I expect) finds jython.exe.

The failure of test_threading I saw isn't the one you have (and I can't repeat mine standalone).
