Wouldn't it be nice if the threads updated their argv[0] to something like
"argv[0]-kernel"
"argv[0]-userspace"
"argv[0]-sigio"
"argv[0]-sigwinch"?

I would send a patch but my first attempt didn't work... Can this be 
done? Maybe renicing the threads could help in environments where you 
have lots of UMLs running? Like having the kernel runnig at -10 and 
userspace at 19 and sigio at 19? Maybe this could make the "time" inside 
UML more consistent in high loads?

Comments?
