embedding octave twice causes warning: duplicate binary operator

[Alain Baeckeroot]

Dear all

We are just starting a project, where we would like to have one octave 
instance (near 100 MB memory used) with a php interface for several 
simultaneous users.

In our idea, 
- octave gets the input datas (read only) from a postgres database (this 
already work) and then
-   each user (probably no more than 10 simultaneous) gives some parameters 
and octave run the adequate functions and draw some nice graphics.

Do this mean that we need to launch one octave process per user ?

As function arguments are passed by value, we thought we could  just call 
one "great_function" per user without problem.  I'm confused now :-) 

Best regards.
