I don't know the exact opinion of the other library maintainers, but 
personally I consider mt_allocator an old experiment, which, definitely, 
to make any sense today would need profound changes. In particular, I 
don't think we can hope to get something useful from it when size_t is 
16 bits and, more importantly, pointers are 24 bits. Thus, my 
recommendation would be just arranging for its code not to break 
bootstrap, nothing more than that.
