Hi,

I've been having problems saving KConfig data from a KControl module 
that's started via the "Administrator Mode" button. What’s happening is 
that the module is started via "kcmshell" with KProcess, and is then 
embedded within the user's KControl.

The problem comes when the module is unloaded - basically KProcess is 
sending a SIGKILL to the "kcmshell" process, meaning that the running 
module never gets to call its destructors. Therefore, KConfig doesn’t 
do a sync() to save the contents.

Would it not be better to have KProcess send a SIGTERM – and then have "
kcsmshell" use a signal handler to catch this, and then destroy the 
KApplication (which would then mean the destructors would be called)?

Perhaps the constructor for KProcess could take an argument specifying 
if SIGKILL or SIGTERM should be sent? This way everything else should 
still work as before.

Ciao

Craig.
