Hi Matt;

The ASYNC enhancements are actually harmless but I agree with the idea 
of minimizing unnecessary risks before a release.

Ext2fs is rather uninteresting for default use but with Aditya's port of 
NetBSD's allocation code, the new BSD-licensed ext2fs is a copy cat of 
UFS1. This means we could start using some enhancements from FFS 
(softupdates sounds crazy but is doable) and we could check some of 
linux's developments (preallocation, Htree) to see if they make sense in 
UFS.

Not as fun as HAMMER, but nevertheless fun ;-).

Pedro.
