For the whole slowness time, AWT thread is waiting for lock held by AWT-XAWT thread, which is runnable and is trying to get some window property
(sun.awt.X11.XlibWrapper.XGetWindowProperty(Native Method)). It really seems
that the OS is congested and some banal native function takes way too much
time.
