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.
