GZip compression in Perlbal

[Brad Fitzpatrick]

Exactly!  That's the approach I always planned to take with adding gzip
support to Perlbal... parallel pre-compressed files.  Then just check the
modtimes must be newer.

I'm against the idea of doing it at serve-time.  If it _must_ be done at
serve time, I'd like to see a Perlbal-owned directory (separately
configured) that holds the on-the-fly compressed files for future Perlbal
requests to re-use.

I don't like all the extra code and complexity that this on-the-fly version
adds.  Seems like a maintenance problem for a solution that's not even ideal
anyway.

The concatenated resource support in Perlbal lays the groundwork for doing
multiple parallel stats at request time, so reusing that to parallel stat
the normal and .gz version would be a good start and should add very little
new code.
