Create a hosting daemon for quicker response times [#338621]

Found this neat php class that seems to have an intelligently written daemon layer : http://trac.plutonia.nl/projects/system_daemon

Should be able to write a simple wrapper for hosting dispatch pretty simply to allow it to run at higher frequency, and adjust the parameters as to how frequently things should happen.

Dispatch already makes sure to only create new processes once the previous ones are finished, and how frequently to create them,
so this should be pretty easy to implement.

Started work on this using node.js : http://github.com/Vertice/node_aegir

Once you have installed ndistro it's ridiculously simple.

ndistro is kind of like drush_make for node apps, and will fetch node.js itself and the libs we make use of.
the script i wrote calls 'drush @hostmaster status' to retrieve the db credentials, then makes a new connection and spins off
new tasks as they become relevant.

it is _blistering_ fast, but could need some better error handling (ie: if db connection dies, re-connect). We might also need
to tune the javascript refresh time because it takes FAR longer for the page to refresh than it does for the task to be dispatched.
