[AGENT++] Process requests in multiple threads

[Frank Fock]

Hi Arnaud,

There is nothing special to keep in mind, just
the usual synchronization of concurrent access.
If the agent crashes there are at least two
possible reasons:

(1) The agent has been compiled with inconsistent
compiler flags (recompile *everything* with a
consistent setting).
(2) Managed objects are accessed concurrently from
two or more threads. Since AGENT++ uses a two
level locking internally, you should use the same
mechanism if you want to update managed objects from
external threads.

Best regards,
Frank
