*If* you are able to reproduce the hang... Otherwise the strace is
perfectly normal, and thus a waste of bandwidth...
Hmm, I just realized that you can run setup under strace! It won't show
any Windows calls, obviously, but it will show calls to Cygwin programs,
which is what you want, anyway. If you could reproduce the hang under
strace, that output might actually be useful. You should only run the
first script, obviously.
