This should work, though it may not with the default shipped
configuration at the moment.  (Which suggests perhaps that
the default configuration should be changed...)

If you create a file (e.g., dhash.conf) with

	dhash.efrags 3
	dhash.dfrags 1

and run start-dhash with "--maintmode passingtone", and "-O dhash.conf",
you should be able to run with 1 (or 2 or 3) vnodes per process.

Yes, this is probably true, thanks.
