That is odd. The system features used by "rock" cache controller are the 
same ones used by "workers 2".

I suggest looking into why "rock" is not usable. It is the best cache 
type for your needs.

"diskd" controller does not support SMP (simple multi-process) which is 
what the "workers" directive turns on when given values greater than 1.

Both No and Yes.

No, in that you cannot just configure "workers 3" on a proxy with a 
diskd cache_dir.

Yes, in that you can restrict the cache_dir line with "if 
${process_number} = N"  conditions so only **one** worker will attempt 
to use that storage location.

See above.
