I applied your patch to FreeBSD8.0 (the box I get on weekend :-), mounted 10
shares, set vfs.nfs.iodmaxidle=10 (to have nfsiod creation more frequently)
and have been running tests for 4 hours -- just to check the patch does not
break anything. No issues have been detected.
It would be very nice to have this patch committed.
