Description:
        I'm not sure this is a bug in bash per se, but it manifests itself
        there. After running a python curses program (btdownloadcurses.py
        from BitTorrent <http://www.bitconjurer.org/BitTorrent/>), bash exits
        by itself. It even prints "exit" as if I'd pressed ^D.  I attempted
        running bash through gdb, and it looks like bash does indeed think that
        it read an EOF, for some reason. This problem does not occur for the
        non-curses version. The same problem *does* occur in tcsh and solaris
        ksh, but not in zsh or sh. I've also tried this on Linux; the problem
        doesn't seem to occur there.

Repeat-By:
        On a Solaris machine, download BitTorrent if necessary, start bash,
        and run btdownloadcurses.py.
