Created an attachment (id=245)
 --> (http://d.puremagic.com/issues/attachment.cgi?id=245&action=view)
invasive changes, array to associative array, dynamic buffer, code restructure

I modified the code to use a hash table, added a dynamic set of buffers, and
reorganized code to minimize code duplication.  I maintained the original
coding style so as to minimize the diff.
