Note the lack of any info on what the `optimization' or `limitation' or
`subsystems' might be.

This might be an excessively vague way of talking about CONFIG_4KSTACKS
and the problems with heavily nested block device chains, especially
with device-mapper in the mix (fixed in 2.6.15); but so little info has
been provided there that we're left guessing. I'm not even sure if
RHEL3's kernel is built with 4KSTACKS; it would have to be a very
early version of the patch indeed, if so.

(Odd that a prolix googler like Peter would make a mistake like that.
Even odder that it's exactly the same mistake he goes on at tedious
length about others making.)
