 I caught some more processes wedged in vm_map today.  I wasn't able to
 get a stack trace because my attempt to chroot into a recent enough
 userland to use crash(8) also wedged in vm_map.
 
 But then after five minutes, all the processes that were wedged in
 vm_map spontaneously unwedged and continued to make progress!
 
 When I next looked, there was nothing wedged in vm_map.
