I noticed this to. Yes the console lock needs to be replaced with
some else. It don't think its going to be good enough for multihead
systems. Also one lock is going to be poor performace. Their is no reason
to lock out multiple VTs. Just the VT that is impacted.

A: Because a nasty coff is bad for your elf.
