General Multiboxing Question - What happens when you cut the head off a snake?

[valkry]

The snake keeps wriggling for quite some time

As for me, I have 4 different hotkeys which sets my leader as 1 of 4 toons. If the leader dies, I punch one of them and alt tab to that window, takes about 1 second to swap i think.

In a lot of cases I find you don't even need to swap active windows. Generally when your lead character dies (at least in WoW) you can still target other players which lets you continue to dps. Also if you are running dps toons that have a battle res like DKs or druids, I run a macro in the dps spam which will automatically cast battle res on my lead toon if it dies.
