That's correct.

But why? You'll just risk to get a reduced connection re-use but never get an 
improved connection re-use ratio.

No it isn't. We've always wanted to add that sharing ability to the share 
interface but nobody has done that work (yet). You can of course help us 
out...

No. It is a single pool and libcurl will try to find an unused that is 
suitable.
