Alas, this doesn't solve the problem always:

	- On DECstations you can call a dxterm (DEC-specific xterm) from an
	  xterm, and the $WINDOWID is still set. So you cannot distiguish
	  between an xterm and a dxterm.

	- ``xterm -e rlogin otherhost'' doesn't define $WINDOWID on the
	  otherhost.

Any solutions for those problems?
