Jeff Peeler 75492cf82b Implement non-default signal handler for SIGINT
Pressing Ctrl-C will stop a build, but does not clean up the /tmp
directory of dockerfiles. Implement a signal handler such that clean up
does occur.

Python apparently ignores signals while calling join on a queue, so
that's why the small modification was needed there.
