Amen, Brother!
Yes, users can do what you said with rsync, but it is important that it
be no more work than specifying a --use-versioning mount option, and
even that is beyond most users (but that is where defaults come in to
help them).
The namespace for the past versions should be as cleanly done as WAFL
does them. Whether space gets freed automatically when space gets <10%
is another mount option. Where we might do better than WAFL is in
allowing touching filename/..../checkin to cause a version to get
recorded, rather than doing it at particular times.

Of particular concern is that the name space should (somehow)
somehow = filename/versions/version_number and ls -l filename/versions ?
allow me to
easily grab version by date, even if the file hadn't changed for the two
weeks before that, and in fact still hasn't changed... Make it really easy to
grab all or some files by wildcard and with a specific revision, even when
not every file changed with that revision.
Oh, BTW. "The slowdown" as I called it is still there. I guess I spoke to
soon. The specific symptom is that the effected process locks for a time,
usually just a second or two, but sometimes a minute or two and and at least
once for many many minutes. I think that the crash (soft lockup) that I
reported earlier is related as well. And it sounds like the comment that
rvalles had about lockups with mmaped files, except that it doesn't lock up
permanently. Just for a second or three usually.
zam, please comment.
one more thing im pretty sure of - the 2.6.13mm3 without any reiser4
additional patches (just clean 2.6.13mm3 as it has reiser4 already
built) is working fine.
i mean, im not sure if this bug still exists here, but im 100% sure i
can write vim files easy without any downtime, so this is big difference.
so for everyone with this bug - try clean 2.6.13mm3 from kernel.org. It
worked for me. i will wait with this kernel for a patch to stable line.
Also - i will test it a little more tomorrow to be sure that this
version is bug free.
