Or is it? The output definitely looks suspicious. Large amounts of code get processed within a microsecond, while update_wall_time() appears to cause huge delays every time it is called: http://logfs.org/~joern/trace Does this output make sense or does it rather indicate some sloppiness wrt. time in the qemu virtual machine?
