I tried that, but when I took down the slave, master took that address,
and I DEFENATLY don't want that!

If I on slave specify the master resource first, slave takes that IP
when starting up, and vise versa for the master. If I specify 'slave
and then master' on the slave node and 'master then slave' on the 
master node, it works as I intended EXCEPT that master takes over the
slave IP when that goes off-line. The slave is intended as a failsafe
machine just in case. Nothing should run on that if it's in 'standby'
mode. It shouldn't even be accessible, ie totally invisible!

That's what I did. I didn't tell master about slaves address (the non-
movable address).

As I said, 'slave' should take 'master's address, but NOT the other way
around...

Version: 0.4.6

The 'info: node master: status up', says that the slave is detecting that
the master is up again, but it don't release the IP... Heartbeat have to
be restarted on the slave, for it to do that...
