This isn't just bug 914925, right?

Looks like that didn't change anything for reftests, so I think it is.

I tried manually patching runreftest.py, and it seems to work. However, using ctrl-c to try break just killed the app, and made my terminal tab stop accepting input.

Looks like this is partially because mach is catching the ctrl-c (SIGINT) signal and exiting.

Disabling this (using signal.signal(signal.SIGINT, signal.SIG_IGN)) stops mach from quitting, but I still never get an (lldb) prompt. It appears to break execution correctly, I just have no way of providing input.
