[ZODB-Dev] _p_oid

[Adam GROSZER]

Hello,

Does anyone know how _p_oid is generated?

I'm asking because we would like to use _p_oid as a unique key to
store BLOB-like files on the filesystem.
Of course more threads/processes/machines are in the picture.
So the question is once an object gets a _p_oid assigned, is it
guaranteed to be unique over all instances accessing the same DB?

thanks
