Hey, guys!
After many attempts pmap function was realized by me. This is 
analogous to taskPool.amap function, but I do not know how much 
he is good. In simple tests, it showed a corresponding 
acceleration. I would like to ask you to advise me options to 
improve this function. If all this makes sense, I can make a DUB 
package.

Why just not use:

I was trying it, but this issue was stopping me.

There is a lot of hacking going on in a lot of code because of this
problem, but even a bounty has failed to get anyone interested in
fixing it.
