GC and Threading

Hi, just two quick question: 1. Is it possible to disable the threading model and have multiple thread to eval the code or have one ECL per thread? 2. Can the garbage collector be disabled at all and have the memory managed in a reference counting fashion?

I like to embed the ECL in my multithread application but I've got very restrictive constrain about thread and memory: * I can not spawn new thread but I've got concurrent thread to execute ecl call. * A component that bring GC would probably not be accepted and I'm wondering if there is an alternative to that in ECL, or at least have more control how/when GC will be run.

Can you point me out where to look in the source code to understand those aspect of ECL?

Thanks in advance. f.
