Thank you all for your help in my computer science educational research trials and errors. 

This helped a lot.

For some definitions of "work", in some deployment environments, one may be able to use such unsupported configurations (e.g., by using configuration macros to create worker-specific cache_dirs), but I do not recommend those unsupported tricks and am not going to detail them here. Sooner or later, those tricks may stop working without notice and with bad side effects.
