/*
 * Interface for small allocations. If you need a little scratch space for
 *  a throwaway buffer or string, use this. It will make small allocations
 *  on the stack if possible, and use allocator.Malloc() if they are too
 *  large. This helps reduce malloc pressure.
 * There are some rules, though:
 * NEVER return a pointer from this, as stack-allocated buffers go away
 *  when your function returns.
 * NEVER allocate in a loop, as stack-allocated pointers will pile up. Call
 *  a function that uses smallAlloc from your loop, so the allocation can
 *  free each time.
 * NEVER call smallAlloc with any complex expression (it's a macro that WILL
 *  have side effects...it references the argument multiple times). Use a
 *  variable or a literal.
 * NEVER free a pointer from this with anything but smallFree. It will not
 *  be a valid pointer to the allocator, regardless of where the memory came
 *  from.
 * NEVER realloc a pointer from this.
 * NEVER forget to use smallFree: it may not be a pointer from the stack.
 * NEVER forget to check for NULL...allocation can fail here, of course!
