> In the coming resource manager, the current model is that all tasks will run as the same
generic user (task.java is called directly by the TaskTracker).
> Instead of calling "java task.java [arguments]" allow for calling a program which will
assume the UID (euid, gid, etc) of the calling user and call task.java on behalf of the TaskTracker.
