if we assume the number of files to be a million (which certainly qualifies
as one of the larger directory sizes one encounters...), and the average
filename length with 20, you'd end up with 20 megs of data. 

Is that really a problem on nowadays several gigabyte machines? And we are
talking a rather freakish case here.
