InterClient is thread-safe, but not multi-threaded. All simultaneous
requests will be serialized (in the meaning used in distributed
systems) by InterServer. So two simultaneous requests will be
executed by server one by one.

Have you tried type 4 JDBC driver? It might be slower, but might
solve your problems. Personally I did not meet any problems in
multithreaded apps either with InterClient, or with our type 4 driver.
