I want to set up a Jenkins Master that will let slaves do all the the builds. 

* The master is just a traffic cop, getting SVN hook triggers and kicking off slave builds.
* There will be about 10 Java Maven build jobs in this setup.
* I wish to run the Jenkins master on a hosted server that has limited resources (RAM).
* I will run the slaves on some nicely loaded machines on my own network.

So my question is how little RAM could I get away with allocating to the Master Jenkins instance? 256M? 384M? 512M? Other?

I cannot seem to find this specific info in the Jenkins docs.
