Chris,

Which version of Orca are you using?

Yes, Orca could be optimized here to remember the information from each
file without reopening it.  I think that data could be saved into the
orca.state file so Orca wouldn't have to do all that work.   Patches
welcome :)  

Also, you may want to keep Orca runnin continuously, so it won't suffer
from the startup costs.

Best,
Blair
