We should be very careful though -- because historically things like memalign
were implemented as dumb wrappers around malloc, they can behave very badly;
here's what the GNU Libc manual says:

      With the GNU library, you can use `free' to free the blocks that
   `memalign', `posix_memalign', and `valloc' return.  That does not work
   in BSD, however--BSD does not provide any way to free such blocks.

I think memalign should only be used for specific system types where we know
it's implemented in a reasonable manner.
