others will give better answers.  I suppose containers (I think 
one of Andrei's next projects) will make a big difference.  you 
can look at the following, which is used by EMSI in production 
(and now based on Andrei's allocator), a company whose work was 
recently profiled by the New York Times.

btw you use nogc if you want to be sure you are not allocating by 
mistake (or track down rogue allocations you hadn't thought 
about).  and it gives users of your code confidence.  but if you 
don't allocate much, you don't absolutely need to use nogc.
