I'll be working on that last problem.  There's lot's of optimization
that can be done w.r.t. weather alert drawing.

I've also been working on how the weather alerts are stored.  It
appeared that the memory space used for alerts kept growing without
bounds.  Expired alert slots weren't getting re-used.  That would
have caused slowdowns as thousands of expired alert slots were
checked while Xastir was trying to find the small quantity of active
alerts to draw.  That situation is now better in the latest code,
but I'm still checking to see whether it's solved permanently.  I
_think_ it is but testing isn't complete yet.
