mode -- mode to open the database with. Valid mode are:
* MODE_MMAP_EXT - use the C extension with memory map.
* MODE_MMAP - read from memory map. Pure Python.
* MODE_FILE - read database as standard file. Pure Python.
* MODE_MEMORY - load database into memory. Pure Python.
* MODE_FD - the param passed via database is a file descriptor, not
a path. This mode implies MODE_MEMORY.
