That was on my list of changes to revisit.. I wanted to get the changes
into CVS as they have been bitrotting locally.

We would need an additional flag to vmem_create, or an ipl argument. I
have a couple of questions:

- Is it useful to call vmem_create from an interrupt handler, or for it
  not to sleep (VM_NOSLEEP)? I can't see how but there are undoubtedly
  other uses I have not thought of.

- Is it intended that the quantum cache could in the future be used from
  an interrupt handler?

Cheers,
