resent because of subscription issues.

I think the following patch might fix the build failures on Debian.  The
idea is to kill the test before the build process kills the whole build.

Let me know if you'd like me to prepare an upload of 0.5+this-patch.

Subject: [PATCH] tests: Add optional use of timeout utility, if present. Add to emacs tests.

The goal here is to treat a hung test as a failure. The emacs test for
sending mail is known to be problematic on the debian
autobuilders. This is both a bandaid fix for that, and a sensible long
term feature.

Currently a fixed timeout of 5 minutes is used.
