    I don't see any better solution.  It is non-trivial to fix the
    behavior of handle_one_xevent with synched input.  I, for one, don't
    see any clean way to fix note note_mouse_highlight and
    x_handle_dnd_message.

Could you tell us about these problems?

    Finally, putting the BLOCK_INPUT's does not seem to affect performance
    noticeably.

That doesn't surprise me--they only do a few instructions
in the usual case.

Would you please install your patch?
