I don't think we need to worry about that, it is probably in the noise.

There will almost certainly be fallout from this change w.r.t. 4k 
stacks. It should probably at least be tested on 4k stacks over a fairly 
complex volume setup to see.

Also with respect to stack usage, is there extra stack space used, in 
addition to the explicit %esp adjustments, to set up each function call?

IOW is the total more than the sum of the parts? :)

I'm glad to hear that there's no apparent performance penalty....
