	Oh, right, sure.  Sorry about that.  We usually do two files in
parallel to beat that.  Each file gets the next allocation, so they
lockstep and prevent each other from getting a contiguous allocation.
	If that's all your doing, why not build two files?  Heck, the
l_count thing could make the tree grow faster too if that's your intent.
