Yes, great! That works. But this was simple and rather contrived
example. In practice it's impossible (or at least impractical) to make
as many clones of the same template object as needed before thay are
used. I would therefore like to introduce a new cache option
"cloned_cache" which will use cached data only as a template for making
clones. I'll try to implement it myself but as I've looked to sources -
it won't be that easy :)

But I think this strategy must already be used for the "shared_cache",
isn't it? Because in that case many processes may use the cached data in
the same time.
 
Regards,
Jozef
