[ic] On restart of IC in rpc mode, 2 IC processes are not stopped

[interch]

I have also run into this on production servers where new catalogs are added
frequently.  This is under both Redhat and Freebsd.  My guess is that it's a
bug in perl because what is happening is that a kill -TERM doesn't work, you
have to use -KILL on the parent and all the children.  Unfortunately I'm not
enough of a perl guru to know how to track it down or fix it.
