Subject: Is "NULLFS" broken?

Dear FreeBSDers:

I noticed that whenever I have "null" mounted file systems, I get 
kernel page faults sometime later.  The system without mounted NULLFS
doesn't generate kernel page faults as far as I can tell.

I am running FreeBSD-2.2/ctm/src-2.2.0139.gz and doing a lot of     
reading and writing to the "null" mounted directory as root.           
I tried FreeBSD-2.1.6.1 and I still got kernel page faults with 
NULLFS mounted.

I am a happy user of FreeBSD for a year now.  I would be a happier
user if I don't get the kernel page faults with NULLFS.  :-)
Am I doing something stupid or the "null fs" is broken?

Please help me solving this problem.
Thank you in advance.
