Cloud9 throws error when spawning child process, is there a workaround?

Confirmed by FAQ http://support.cloud9ide.com/entries/20862101-cloud9-throws-an-error-when-i-run-code-that-spawns-a-child-process-why cloud9 does not support spawning child processes in a shared environment. Is there a workaround to this?

Or can you just no longer use cloud9 if you need to spawn child processes? Seems like there must be some way for this to work?

The only way (at the moment) to do this is by installing Cloud9 locally (see GitHub page).

edit Cloud9 now has resolved this problem by providing a VM per project.
