Put tmp files in an external dir with Ember?

In Ember.js projects I always find it so disruptive that ember server creates such a massive dump of rapidly changing files to the tmp folder in my project directory.

I often create projects in a cloud-synced folder, so these files tend to hit my daemon over the head with a mallet.

Also, it messes up my IDE's indexing and I have to manually exclude it every time.

Is there a way to configure to run ember s to put tmp outside of my project directory? Putting it into /tmp or ~/.tmp would be great.
