[pony-build] in-memory db stuff

[Max Laite]

Alright, bare with me on the following...

So first dbsqlite.py is using the *.db arg you specify when going to run
(opens it according to code... )....

Then it passes the shelve file to IntDictWrapper and we get the
following....
IntDictWrapper object at 0x101e0f350

IntDictWrapper.....I am only going by name but is it Initializing stuff for
the sending of data in dictionaries?

So after IntDictWrapper call, dbsqlite.py shows the dbfile as catalog.sqlite

All I can tell from the catalog is it holds the 'MAKE_SHELF' Line 34 in
dbsqlite.

Then what the Coordinator is using finally for dbfile arg is IncDictWrapper
object 0x101e0f350

Can you explain any of those step in server startup a bit more?

When ever i see 0xjibberish I always figure memory address......
