 Summary:
 
 - This is the result of a short-term memory allocation failure with
   KM_NOSLEEP in soft interrupt context.
 
 - The problem remains in netbsd-10.
 
 - Requires change to API contract in thmap -- either must be able to
   fail, or must be allowed to sleep and therefore must be forbidden in
   (soft) interrupt context or under locks held in (soft) interrupt
   context.
