Re: [PATCH] Fix futures, %worker-count shouldn't be zero to prevent halting

Processor count can change over time. So, current-processor-count needs 
to be called only once (or there needs to be proper support for adapting 
to the changing count). It's current-processor-count, not 
fixed-processor-count, even if in most cases it doesn't change.

Also:

(max 1 (current-processor-count))
