  Using:  libudisks2-0:amd64 2.1.6-2ubuntu1
  
  Ubuntu 4.2.0-36.42-generic 4.2.8-ckt8
  Description:	Ubuntu 15.10
  Release:	15.10
  
  When I add USB drives to my system I end-up with udisksd using 100% of a
  core shortly after. After some time this goes up to 200% (in one step),
  so using 2 cores. Thread view shows CPU time of CMD 'pool':
  
  # ps -T -p  <pid-of-udisksd>
    PID  SPID TTY          TIME CMD
  26229 26229 ?        00:00:00 udisksd
  26229 26230 ?        00:00:00 gmain
  26229 26232 ?        00:00:00 gdbus
  26229 26233 ?        00:00:00 probing-thread
  26229 26234 ?        00:00:00 cleanup
  26229  3325 ?        00:33:16 pool
  26229  5027 ?        00:03:00 pool
  
  
  My solution is to kill it and let it restart.
  
  Strace needs to follow threads to show activity, it's then flooding
  with:
  
  # strace -p <udisksd-pid> -f
  [pid  3325] poll([{fd=12, events=POLLIN}, {fd=17, events=POLLOUT}, {fd=18, events=POLLIN}, {fd=20, events=POLLIN}], 4, 0) = 2 ([{fd=12, revents=POLLIN}, {fd=17, revents=POLLOUT}])
