For SQLITE_OPEN_SHARED_SCHEMA connections, the
SQLITE_DBSTATUS_SCHEMA_USED sqlite3_db_used() distributes
the memory used for a shared schema object evenly between all database
connections that share it.

## Implementation Notes

A single Schema object is never used by more than database simultaneously,
A single Schema object is never used by more than one database simultaneously,
regardless of whether or not those databases are attached to the same or
different database handles. Instead, a pool of schema objects is maintained 
for each unique sqlite_master-contents/schema-cookie combination
opened within the process. Each time database schemas are required by a
connection, for example as part of an sqlite3_prepare\*(),
sqlite3_blob_open() or sqlite3_blob_open() call, it obtains
the minimum number of schemas required from the various schema-pools, returning
