Just as two data points here: Solaris attempts to provide coherent file sizes
in /proc (at least to the extent that tried a few for objects where it is
remotely possible), and the Linux 2.6.12 kernel I have on a box locally
basically doesn't.

My view is that it's a synthetic file system with data that varies dynamically
at runtime, and that while it wouldn't hurt to produce file size information
that's correct, it's quite a bit of work to do so and that I wouldn't
prioritize it above other, more critical things that need to happen. We
should certainly evaluate any patches that come in for possible inclusion,
assuming they don't muck up the internals of procfs too much; it's not clear
to me if they necessarily do so or not.
