That is the kind of responsiveness I expect, and what other people
I've discussed this with experience, which is why I think it is
something unusual in my setup or environment...  Unfortunately, I'm
currently unable to find it myself, and can reliably reproduce the
issue even in a virgin environment.

So far, the only common factors (that I see) across each of these has
been my Linux host, (CentOS 5.8 at present) and my various
tabs/accounts.  However, I am at a complete loss as to even guess at
how these could affect page faulting on the X server.

For reference: on the Linux host, when the Windows host is
experiencing these page faults, the Linux host is reporting 20-30% CPU
usage overall, no swap usage.

Similar, to but different from Larry's suggestion, can you install Firefox on CentOS using the installer from Firefox itself, and not the distro version? I can imagine it could be something about flags or settings they used when compiling it.
