FWIW, these symptoms appear to be the same ones that nickle
exhibits: works fine when input is not from a tty or console, but
otherwise hangs after displaying its prompt. I reported the problem
to the cygwin-ports-general list (nickle is a cygwinports package).
The reply from Yaakov was that he could reproduce the problem but
didn't have a solution and didn't have time to investigate much
further. I looked briefly at the code, but didn't get very far and
haven't had time to look further either.
