Yup. This is not a heavily loaded system. I'm not doing an excessive amount 
of shared memory stuff as well, and I am not using sysctl tweaks that effect 
shared mem. The thing is completely default (well, almost, I bumped up 
NMBCLUSTERS and maxusers, and I trimmed the kernel config to excluse stuff my 
laptop simply doesn't have or will never have, like some NIC's and SCSI 
adapters). The machine is a desktop machine that runs KDE 2.2.2 (the testing 
tarballs, see freebsd.kde.org for more info) and actually nothing more.

So that's actually why I posted it. It struck me as strange as well that this 
should appear, because I've never seen it before. Also tweaking other vm bits 
seems not good, since the VM really does a good job in balancing itself 
already. I shouldn't mess in something that already works.

Vail's Second Axiom:
        The amount of work to be done increases in proportion to the
amount of work already completed.
