Log Message:
PR kern/38927: processes getting stuck in uvm_map (cv_timedwait), hanging
machine

Assume that a vnode (and associated data structures) costs 2kB in the
worst imaginable case. Don't allow sysctl to set desiredvnodes to a
value that would use more than 75% of KVA or 75% of physical memory.
