I doubt it would improve performance with our current code, but it 
should be benchmarked.

There is this:

   int posix_memalign(void **memptr, size_t alignment, size_t size);

However, some older Unices might not have it so we need a fallback.  In 
the same man page it mentions two obsoleted functions (memalign() and 
valloc()).  Failing that we'll need to fall back to malloc().
