I've got MythControls, MythDVD, MythGallery, MythGame, MythMusic, 
MythNews, MythVideo, MythWeather, and MythStream (not MythStreamTV) 
installed (and MythWeb, but that doesn't even touch mythfrontend).

I just went in to MythWeather and got this while it was displaying the 
weather:

  PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  
COMMAND          
  660 root       9   0 59972  19m  12m S  1.3  3.8  49:12.06 
mythfrontend     

and after

  PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  
COMMAND          
  660 root       9   0 59976  19m  13m D  1.3  4.0  49:12.94 
mythfrontend     

Happy hunting.
