Temporary signal handling.

"Temporary" because it will not work on platforms which don't have real
signals (Hello, Win32) but nevertheless useful, as otherwise gcov (the
code coverage tool) will not count executions of processes that are
killed by signals (in particular, the server processes started in the
tests).

A brief experiment suggests that we're up to about 80% statement
coverage from our 20 tests.
