No, but there's a way to do popd without causing the csh to change to the
directory being popped.

} 	The problem was that my directory stack was "/ /mnt/etc".  I was
} allowed to umount /mnt because while /mnt/etc was in my dirstack because it
} wasn't actually the current directory of any proces, but I couldn't clear
} the dirstack because a popd would try to cd back to /mnt/etc which no
} longer existed.

To remove a bogus directory from the stack, use

	popd +N

where N is the stack position of the bogus directory.  Position 0 (zero) is
the top of the stack.  In the example above,

	% dirs
	/ /mnt/etc
	% popd +1
	/
	%

For those interested, pushd can also take a +N argument, which rotates the
directory stack N positions.
