Running DRb in the main thread?

Laurent Julliard

I was wondering if there are some low level API that I can use in Drb
to make it run as the equivalent of an "event loop" in the main thread
of a program rather than having DRb starting its own thread as it does
when start_service is invoked.

The reason for this is that I need to run a remote program without
disturbing its original list of threads. So running "synchronously" in
the main thread would be ok.

Advices and ideas are welcome

How about using ThreadGroup to organize your threads?

It doesn't solve my problem because what I want is to avoid disturbing
the scheduling of the original threads.

I looked at the code and it looks like the only way I can do this is
by rewriting the main_loop method of drb/drb.rb in my own program.
