OK, something like this?

			IHAVE	CHECK	TAKETHIS
xferred OK:		235	NA	239
send article:		335	238	NA
not wanted:		435	438	[438]
xfer not possible:	436	431	[431]
xfer failed:		436	NA	[431]
xfer rejected:		437	NA	439

Simply reusing 431 and 438 for TAKETHIS.  This might invalidate your 
argument that the response codes need to be unique between CHECK and 
TAKETHIS, but I don't see where this breaks anything.   My guess is that 
a client wouldn't be pipelining CHECK and TAKETHIS together.  The client 
will pipeline the CHECKs, and process the results.  Then based on these 
results, it will pipeline TAKETHIS.  Am I missing something?  Hmm,
even if a client *does* interleave CHECK and TAKETHIS this might still 
work (with a side-effect of trying TAKETHIS twice on an article that the 
server doesn't want).
