How about having something outside the build process do the
monitoring, and kick off a build only when it sees a change?  Your CI
server probably has a way to force a build with a program or script.

You could still run the monitoring process in the build server if
that's important, it would just be a separate build.  The full project
build wouldn't happen on a schedule, but only when requested.
