yes, this can be used in this context. It creates multiple bridge
objects that can run on different cores of a machine.

The memory is shared between the bridge processes, and so you are
limited to simple data structures (no objects or structures, but you
can use arrays of int, real, double, etc.). Although for the complex
data structures, it is possible to save the input/output data
structures in a save file, restore them in the bridge session, run the
processing on it, save the outputs in save files and restore them back
in the main session.

I've used it many times, but since a cock up in the installation of
IDL v8.0, it no longer works on our main CPU machines (32 core
machines). Although it does still work on the IDLv7.2 on these
machines. I have not been able to work out why IDL v8.0 doesn't start
the Bridge process.
