We should assign this bug to an overarching component/project as
multiple independent services (media-hub, location-service, dbus-daemon)
are affected.

However, one idea that came to my mind: It might be that a spurious
posix signal is causing these issues, probably a SIGHUP somewhere,
arising on a thread that the respective signal is not blocked on. I will
keep on investigating into that direction.

Title:
  Apps and services use large amount of CPU after unity8 resets

Status in Media Hub:
  Triaged
Status in “dbus-cpp” package in Ubuntu:
  New

Bug description:
  I noticed that media-hub-service can get into a state where it uses a
  large amount of CPU.

  Steps to reproduce
  1) Start music-app
  2) Play music
  3) Pause music
  4) Close the music-app
  5) $ pkill unity8 (to emulate unity crashing a resetting)

  Notice that media-hub-service is now using a large amount of CPU, note
  this [0] is the media-hub.log at the time.

  The device has to be reset to get the CPU usage back to normal.
