What allocators do you want in std.allocator.showcase?

[Andrei Alexandrescu via Digitalmars-d]

I've put together 
http://erdani.com/d/phobos-prerelease/std_experimental_allocator_showcase.html, 
which is a module containing typical, ready-to-use allocator instantiations.

The basic idea of showcase is to offer allocators that are as easy to 
use as calling a function or using a type - no assembly required.

I've seeded it with a super simple stack front and a mmapped list of 
regions. I have about half a dozen more of usual suspects.

What would you like to see in there?
