Another CI build execution model, is to allow some time for additional changes to arrive in the repository before building to ensure that a developer has checked in all changes associated with the bug, feature, etc. This can help reduce failures.

Having a configurable monitor to allow for repository "cool off" would be a handy feature in Bamboo. Something like: Check for changes every 5 minutes (Bamboo obviously has this) - but then start a configurable countdown. If no additional changes are found in the next 3 minutes, execute a build. If changes are found, restart the countdown.

I "think" CruiseControl offers this functionality. Other commercial CI apps don't seem to offer this by default.
