Sorry. This is my bad. I translated your: "Otherwise looks ok to me."
- to an ack. And I was pretty sure you didn't want to staticize the
local array. I should've known better. I should have waited for your Ok
to leaving the static out before adding an ack.

Ok. I see your point and it sounds reasonable.

It would be great to get this in, it has been respinned quite a few
times already... I hope Lee takes the series in when he's back from his
leave - but it is not a problem for me to change this with later patch
(or change this in the series if it still needs to be reworked).
