sometimes mReferenceCount in SQLiteCloasable.java has some huge number
(a memory address probably)
this causes a database.close() or sqliteStatement.close() to randomly
fail and not release the object. and that usually causes a finalizer
warning or sqlite to return error "dbclose failed due to
unfinalised statements"
