Shouldn't the same effect be achievable using an xterm escape sequence?  I'm
using that capability with awm to redefine the "cd" command so that it causes
the window and icon titles to follow the current working directory.  The
aliases I use to do this look like

    alias xheader 'echo -n "^[]2;\!*^G"'    # sets window title
    alias xiheader 'echo -n "^[]1;\!*^G"'   # sets icon label
    alias cd 'cd \!* ; xheader "${Host}:${cwd}"; xiheader ${Host}:`basename
    $cwd`'

Note:  "^[" and "^G" must be the single control characters ESC and ctrl-G.  The
character strings "^[" and "^G" don't hack it.

There is a bug in awm when the "icon.labels" resource is turned on, which
prevents the icon label from being updated when it changes (it sticks with the
icon name in use when the window was first iconified).  However, with the
uwm-style icons, the above escape sequences work fine.  I haven't tried any of
this with twm, but this is a really handy feature.  It merely requires that the
window manager pay attention to the current values of the window and icon
titles.  (Presumably xterm is sending some kind of an event to the window
manager?)
