Comment(by anonymous):

 Sorry, I just got around to seeing this.  I agree with cnewbold.

 I think the alignment should be align(max(min_size, min(requested_size,
 sizeof(max_type))), 2).

 I'm not familiar with other platforms but on x86/x64, sizeof(max_type) is
 now 32 bytes (for the new AVX instructions from Intel).
