	This is correct, and believe it or not i'm even using
	2.4.19 + rmap15a, no other patches.  I don't have my hard
	numbers available, but the difference between builds was quite
	significant, something like:

	2.4.19 vanilla:
	real 85m

	2.4.19-rmap15a:
	real 102m

	This applies to me as well.

	My build volume is formatted ext3, no htree.
