No, it's Linux (i386 machine, Debian "woody" with 2.4.x kernel)

No, I would not like to do that.  However, I see another possibility.
When failover occurs, the first thing that happens is that the cluster
IP address is released.  The transport agents use the real IP address
of the machine.  If there is a way to make the transport agents use
the cluster IP address instead, then I would imagine that, when this
IP address is released, the transport agents would immediately die.
