Re: kern/56516: pgdaemon spins despite lots of memory available

I got a tip to reduce kern.maxvnodes to about 1/10 of the current
value, and YES, this makes pgdaemon no longer hog the core:

jonsvatnet# sysctl -w kern.maxvnodes=12000
kern.maxvnodes: 110592 -> 12000
jonsvatnet# 

load averages:  0.05,  0.13,  0.50;               up 4+12:48:33      12:34:09
162 threads: 10 idle, 151 sleeping, 1 on CPU

 1515  1515 haldaemo  85 poll/0      9:10  0.00%  0.00% -         hald

So ... this probably gives a lead to what's really causing this?
