We would like to make use off git polling more than it does now.
We've selected to poll every five minutes for changes because we commit a lot.
Our projects take approximately 50 to 70 minutes to build and we've got over a dozen machines that can build for us.

What we would like is that every five minutes a build would start if there are changes, but this doesn't happen. We've selected Execute concurrent builds if necessary (beta) but git doesn't start the actual polling again after the build is done.
