I have been experiencing same problem with my 13-CURRENT amd64
VirtualBox VM for about a month. The conditions that the problem
happens are unclear and all what I can say is

* It happens only after I login in the VM and do something for a
  while. If I boot the VM and shut it down immediately, it never
  happens.
* When the problem happens, one or more unkillable processes seem to
  be left.
