description:
Set default number of vnodes to 1k instead of 64k: a large default
reserves a large amount of memory by default and this is not
desirable in a rump kernel where the typical usage is minimal.
Maybe I should write a few lines to autoscale desiredvnodes up to
a hard limit after the soft limit is reached?
