Doesn't revert to shell after receiving SIGTSTP

[pafoster]

First off, thanks for developing this amazing library!

Unexpected behaviour: If I issue a kill -s SIGTSTP $pid as a command in a separate terminal, the terminal running the UI continues to display the UI (albeit in SIGTSTPed state). Expected behaviour (see top, links and other utilities) is for the running process to revert to the user's shell.
