Unless there's a significant performance impact incurred by using an
allocator globally (for example, under DCE/RPC, rpc_ss_allocate() is 
definitely not interchangeable with malloc() and is somewhat slower)
then I think there exists a strong argument for using the same allocator
everywhere. (Think debugging and performance; I know of a commercial
directory vendor that pretty much just changed the malloc library and
increased the version number a whole major version :-))
