* Add siege-like behaviour to ApacheBench; output the results, as they have

    accrued so far, when the user interrupts with ctrl-c. As the signal handler
    is non-reentrant, we don't need volatiles, and the operations all look
    signal-safe.

  * Update the base version, since handling a signal differently is an external
    API change of sorts.

  * set the LastChangedRevision svn property, as ab.c has $Rev $ embedded, so
    it really should be.
