nfsiod now runs as a kernel process and is control by these sysctls:
It looks like setting vfs.nfs.iodmin=0 and then klling them off works.
We probably should think about changing the default to 0 and setting
appropriate values via /etc/rc.d/nfs. Over all, I can't say this is a
very high priority though patches would certaintly be accepted.
Any statement of the form "X is the one, true Y" is FALSE.
