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.
