I finally read this part of the message.
This is a remarkably complicated way to go about deleting the window text!

Here is a simpler one:

	echo -n , >/mnt/acme/$winid/addr
	echo -n >/mnt/acme/$winid/data

(Or on Unix:
	echo -n , | 9p write acme/$winid/addr
	9p write acme/$winid/data </dev/null
)
