Hi John,

Could you explain more on this ?  Is calling g_idle_add() from
"NON-GUI" thread important ?   I think no matter which thread invoke
g_idle_add(),
the idle callback will be associated with default main loop, am I correct ?

Did you put a g_usleep() in your idle callback ?  If not, how did you avoid
the idle callback to take all of the CPU loading ?

Thanks
