Hello,

I reconstructed venti and fossil from the scratch using the copy in kfs:
- first time (at the time my system is damaged by typhoon)
	I constructed auth+venti+fossil server from old machine that had been
my file server.
	HDs were old 8GB + 8GB.
- second time ( at the first corruption of fossil )
	I reconstructed auth+venti+fossil server using the copy in kfs, not
from arenas.
	Although I suspected the origin of the trouble is in old machine:
		P3/Xeon/866 with 256MB memory
- third time (at second corruption of fossil )
	I replaced the old machine with new machine (Athron 2200+ with 512MB
memory) but 	HDs were still old.
	I reconstructed the server using the copy in kfs, not from arenas.
	Although I suspected the origin of the trouble is in old HDs.
- fourth time (at third trouble of fossil )
	I replaced old HDs with new HD (80GB).
	arenas and fossil are constructed from the scratch.
	I expected fossil can run without trouble.
- fifth time (at fourth trouble of fossil that were happened at mid
night dump)
	I simply execute:
	checkarenas
	checkindex
	flchk
- sixth time (at fifth trouble of fossil )
	I simply execute:
	checkarenas
	checkindex
	flchk
	and posted the problems to 9fans

In constructing arenas and fossil I got new version of fossil and venti
binary
from sources.cs.bell-labs.com and used them as it is.

They are:
