    The reason for the timer is to avoid hanging.

In what cases would it hang?  Are these old xterm versions?

    The query is used to find out the version of xterm being used.

    If we just send the escape sequence to enable modifyOtherKeys on a
    terminal that does not support it, the escape sequence will appear as
    junk on the screen. 

Emacs clears the screen at startup.  Maybe it is ok if that happens
on old versions of xterm, until they are replaced.
