This assumes (1) that the Ada vendor's allocation code is efficient,
and/or (2) that the platform's malloc is not.

Verdix tried that in the 1980s--and the results were dismal.
Their fix for serious heap fragmentation problems was to tell
us the linker commands/pragmas to make 'new' bypass their
code and go directly to malloc.
