Personally I consider this to be a good thing for libraries.  It is useful
if you want to use a different (underlying) memory allocation API.
Imagine you want to pass part of a shared memory arena (IRIX uses such)
and tries to free() it with the standard libc call, this might 
fail and crash the program.  Also M$-Windows knows different
memory allocator APIs.
