I've just skimmed the paper.
It seems that all this does is to defragment the memory at 
runtime.
Which it does at regular intervals unless a steady-state 
heuristic stops mesh from doing that.
It also seems this allocation scheme only works for small to 
medium size allocations done in large quantities.
And therefore would not work if the application does allocation 
in large chunks itself (as is the case for dmd by default).

I am going to look into this a bit further.
