Ok, how's this for a bug:

SYMPTOM:
	when using ed(1) on a file that is on a filesystem that is NFS mounted
	from a remote host, every second 'w' (write) fails with a '?',
	starting with the first. every other 'w' succeeds. Bizarre!

SYSTEM:
	386/ix 2.0.2 with NFS over TCP/IP.

REPEAT-BY:
	cd <nfs-mounted-directory>
	ed file
	w				(will fail with '?')
	w				(will succeed with '0')
	w				(will fail with '?')
	w				(will succeed with '0')
	etc etc

	Note: if 'file' existed already, you'll get a different number than 0;
	but otherwise it's as above. ed diagnostics don't help much.

Anyone got any clues on why this happens and perhaps a fix?.
