Coming back to this, having tested this quite a bit I think this is just 
an issue with null mounts on NetBSD.  Even in simple tests where I e.g. 
mount a bunch of loopback mounts, ls them, then unmount, I'm seeing the 
system grinding to a standstill and sometimes hanging.

For example right now I'm trying to simply unmount a bunch of null 
mounts (not using bob), none of which are nested, and:

 PID USERNAME PRI NICE   SIZE   RES STATE       TIME   WCPU    CPU COMMAND
   0 root     124    0     0K  350M CPU/4      40:33 57.28% 57.28% [system]

on an otherwise completely idle 16 core / 64GB system.

As bob tries to do everything in parallel this may be pushing it.  I'm 
running 10.1, but I don't see any changes to nullfs in 11.

Ideas on how to improve this welcome.
