| This may be a dumb question, but why the hell did the process use up all 
| the CPU time while it was waiting? 
|  
| I tried attaching to it with gdb and with truss, but I got no information. 
| I guess it is some kind of overflow, that caused the process to execute one 
| instruction repeatedly (only guessed, I'm not an expert). 
|  
| If it is an overflow, the cause must be in the environment. KDE was just 
| starting up, it did what it always does on startup.
