clusterssh runaway process on start

Hash: SHA1

Hi Ben,

Does the problem exist when running another window manager? I suspect the issue
may lie in the interaction between perl-tk and the WM, or in a change to the
terminal emulator being used. It sounds as if the issue is occurring when CSSH
attempts to open a terminal.

Thank you,
Tony
