I'd like to know if any of the current imageboard software packages available support threaded execution. I've just finished making the regeneration of the board front pages and thread res page regenerate asynchronously with shared object memory, and I'd like to see if anyone thinks there is already a software package out there which also supports this, before I start flaunting it around as a major feature.

If anyone would like to view the large diff which contains the threading code, you can view it here: http://code.google.com/p/pyib-standalone/source/diff?r=18&format=side&path=/trunk/post.py
