Now I realized another strange problem. A couple of WindowNaker dock 
applications sometimes can't start normally. Today doesn't start wmmon 
and wmbsdbatt. They actually started but nothing shows in the dock.
Attaching to the processes reveal similar things. They waited for 
something in poll(). Right after 'continue' in gdb, their windows 
started to show what they should. What's happening? Maybe this is an X 
issue? Or 'device radeondrm'?
