If this code is still going thru the inndcomm interface, it won't work for
NoCeM's needs.  The ctlinnd/inndcomm interface can only handle one command
per pass through the INND main select loop, and this is nowhere *near* fast
enough to handle the volume of cancel requests needed by the current volume
of NoCeM traffic.   You need something that can let the requests "stream",
like the proposed solution Olaf Titz mentioned, or something that lets you 
handle multiple cancel requests in a single inndcomm transaction (I did this
once, but alas that source tree disappeared a long time ago :-(.
