firehose polling system

[Colin Walters <walters redhat com>]

Hi,

Over the last few days I've been trying to design and code a new polling
system for Mugshot.  The main goal is to reduce the database traffic
we're currently doing now checking for updates.  This in turn should
improve the Online Desktop server by helping it stay up longer.

It's called Firehose.  The current design page is here:

I'll commit some code soon to the Mugshot SVN.
