Re[fdo-users] turn geometries

[surrounded]

OK, so I feel dumb - it struck me that the reason this is happening because I
reset the value of the byte[] array everytime I go through the loop.  It's
not that only one is being returned, its that I rewrite the byte[]
everytime.

Perhaps I'm too close to this code - thanks for the help, sorry for wasting
your time.
