Gosh, while we can investigate this, we should not do it because of a
random stupid bug on Solaris. If build times are within a few % of
the non stamp build, then it would be reasonable, if they are 4x
longer, then I am in no way in favor of doing this. Making this type
of decision without supporting data would be bad.
