They are not completely harmless.
Is your system loaded ? There was a change in -current that causes the 
interrupts of your input device (mouse or usb) to be delayed longer than 
before on a buzy system. This makes the wsevent flow get out of sync, 
causing these errors.
Then the X server is calling printf() to display these messages inside a 
signal handler, which is bad and can cause other corruption in the X 
server.
So I think that this is something that should be fixed before 3.9.
