I think an option to deactivate might be good, i.e., active by default (note 
that the option would be for qt4-libs).

Is there a way to prevent the package (kdelibs4?) from installing if maxfiles 
is set too low? That way you cannot ignore the message. We also need a warning 
about the soft descriptor limit, which probably should not result in an 
install failure as it is a user limit.

My laptop is running a kernel with MAXFILES=16384 (lsof shows ~9300 open 
files). I don't see that number being intrinsically any more or less gross 
than 3404. It is simply what is needed to run KDE efficiently.

PS My system has memory leak that requires a reboot every few days. I think it 
is caused by an experimental memory allocated that I'm using for the iwn 
network driver. It is, however, possible that it is related to the large 
number of open files. It might be something to watch out for. The symptom is 
the use of swap space under normal conditions.
