Also, does Bitcoin open the BerkeleyDB as exclusive, precluding the need for a file lock?It does not -- did my own tests.
Is there a way to open BerkeleyDB exclusive?
DB_PRIVATE is the worst of both worlds. DB_PRIVATE is not exclusive, but it does make it get screwed up if another process tries to access it at the same time.
I've dropped the DB_PRIVATE flag in rev 153.
