VM laundry size is always 0

[Igor Pokrovsky]

Hello!

I’ve got strange values for vm laundry size on -STABLE.
And these values do not change even under load.

vm.domain.0.stats.laundry: 0
vm.stats.vm.v_laundry_count: 0

I cannot complete buildworld on this box, compiler throughs segmentation core at some random points.

I tested RAM and hard disk for errors - none found.
Has anyone seen this? Relevant boot messages follows.
