Not a bug in the ext3 code, but if a RHEL5 or SLES 10 or Debian etch
user uses EA-in-Inode, with SELinux enabled, and then uses the e2fsck
shipped with their distro, some of the unsorted EA's would get
deleted.... right?  

If that's correct, then that's a pretty nasty data corruption problem
(that with SELinux enabled could cause the system to become completely
non-functional, further contributing to SELinux's bad reputation...)
and we'll need to push your patch to the various distro's as a
relatively high priority bug fix.
