Hi --

When terrasync is running, are the updates atomic?
I suspect not, since terrasync depends on svn, and
AFAIK svn commits are atomic but checkouts are not.

I've seem some pretty weird irreproducible results
which might be explained by FG reading half of a
new file plus half of an old file because terrasync
was in the middle of an update.

So far this is mostly just a hypothesis, but it fits
the facts, and I haven't been able to come up with 
any other hypotheses to explain what I've seen.

As an example, FG died via an assertion in navradio.
The runway was numbered "0".  Needless to say, the
airport in question doesn't have any such runway.

I hear rumors of a major upgrade/rewrite to terrasync.
This might be something to keep in mind.
