RHcloud deploy is slow

[cben]

Following up from #57 (comment).
git push rhcloud takes ~7min :-(
Luckily it doens't cause downtime because I'm scaled to at least 2 gears, and they're upgraded one by one.

I could add .openshift/markers/hot_deploy file which I thought is bad because it doesn't restart server.
But Openshift runs nodejs under https://www.npmjs.com/package/supervisor (unless I add .openshift/markers/use_npm, which also prevents hot_deploy) which should restart on hot deploy:

A little supervisor script for nodejs. It runs your program, and watches for code changes, so you can have hot-code reloading-ish behavior, without worrying about memory leaks and making sure you clean up all the inter-module references, and without a whole new require system.

The deploy code is at https://github.com/openshift/origin-server/blob/master/cartridges/openshift-origin-cartridge-nodejs/bin/control

This slowness is root cause of #115 (deploys / scaling fail by timing out).
Closing this as a separate issue.
