Please make it so that you can easily write thread-level 
allocator agnostic code without passing the allocator around. 
E.g. so that you can start writing code with GC, but properly 
release memory, then when you are certain that your model does 
not introduce cycles replace it with a cheaper allocation model 
with no additional code changes.
