It is exactly what happened.  And I have just reproduced it using:
    echo "ctlinnd rmgroup newsgroup.test" | mod-active

We could introduce a new keyword "ctlinnd overview" to handle external calls.
It would be better than nothing.
I see we already have "ctlinnd addhist" which can be used for history.

    ctlinnd overview delete newsgroup?
    ctlinnd deloverview newsgroup?


In mod-active, we would then have:

    ctlinnd pause 'batch active update'
    ctlinnd reload active 'updated from checkgroups'
++  ctlind deloverview newsgroup1
++  ctlind deloverview newsgroup2
    ctlinnd go 'batch active update'


The command can be sent when the news server is paused/throttled.
