Strange freezing continues, probably blanking should be left alone:
1. while reading random patches with gitk with nothing more running. gitk already read all patch headers from the whole Linux git archive.
gitk stops reacting on mouse clicks "Ctrl+Alt+1" (switching to virtual desktop #1 in evilwm) -- OK "Ctrl+Alt+2" (back) -- gitk shows its window but without actual content as if something can't get a timeslice for redraw.
2. Two allmodconfig builds in parallel. mutt downloading email, /me lazily browsing with Firefox.
