I wouldn't mind much if it would do it randomly sometimes, but the point 
is that it will continue to do it with 30sec interval regardless of the
disk activity until I reboot the machine.

Same about issue #884 - it's not _very_ big problem if there is temporary 
performance problems (of course these should be fixed as well), but the 
point is that there is permanent damage done from which you can't recover 
normally (reboot isn't normal IMHO :).
