Why don't you use 1.4.X or 1.5.X? They are much lesser feature-rich
compared to -current and even smaller in sizes. Why weren't you
against UBC when it was committed for the first time? There are a
number of features that will make the kernel even bigger by _default_
to be committed in the near future, such as new pipe, kqueue, etc.

Has Linux evolved in a wrong way? I don't think so. It has a number
of features and advantages NetBSD doesn't yet (no, I don't want to
start an OS holy war here).

I'm surprised at so many objections to addition of such a little
feature to the kernel which I think good to have.
Anyway, in order to satisfy more people it should be:
* configurable at compile time via
* able to be disabled with sysctl(8) or wsconsctl(8) once it's
compiled into the kernel.
* machine-independent, hopefully
