[Serusers] Location table memory usage

[Jan Janak]

Actually not. location table is using shared memory to store the data,
PKG_MALLOC controls the private memory. User location table needs
private memory only if you startup/shutdown ser or during intensive
communication with the database.

I managed to have more than 500.000 entries in the location table on my
laptop with 256MB of memory and the memory was still not an issue.
