Well, by that argument, 1% of kernel size doesn't matter either..

1% of a kernel for an embedded device is roughly 10-30kB or so depending
on how small you make the configuration.

If that matters, then so should the difference of 3-8 processes' kernel
stack usage when you have a 4k/8k stack choice.

And they _all_ will have at least 3-8 processes on them. Even the simplest
ones will tend to have many more.
