Re: Formal Review of region allocator begins

[dsimcha]

BTW, forgot to mention it.  This proposal also includes a gcallocator 
allocator struct that just wraps stuff from core.memory and std.array. 
The docs are at 
http://cis.jhu.edu/~dsimcha/d/phobos/std_gcallocator.html and the source 
is at the same place as for regionallocator.
