Just a follow up.  The .db files are 1.85 berkeley hashes as created
using postmap:

jonah% file mynetworks.db 
mynetworks.db: Berkeley DB 1.85 (Hash, version 2, native byte-order)
jonah% file virtual.db 
virtual.db: Berkeley DB 1.85 (Hash, version 2, native byte-order)

I don't see any evidence that the virtual.db map is failing at all so I
am reluctant to think that it a problem in the db lookup code.
