   I'm experiencing situations, where my Shark, updated to 6.1.5,
   can't exec or fork or otherwise change the mappings of processes
   anymore. E.g. I start

   date

   in a pre-exsiting shell, and the process hangs in vm_map forever.
   Especially annoying is that killing other processes hangs, too, so
   the only fix is to hardware reset, including full fsck.

Sounds likely to be related to these:
