Some of the generators (including Argument Clinic) are themselves written in Python, so building the checked in version first is the only way to be 100% sure you have a compatible version available. As Serhiy notes, the robust fix is to make sure the generators leave the file modification times unchanged if they don't actually change anything, either by working entirely in memory and only writing the result back out if it changed, or by generating out-of-place and then doing either a rename (if the result changed), or deleting the new one (if it is the same as the original).
