Using a prototype system we have generational copying, mark & sweep, reference counting, and their variants. We are not sure if our approach conflicts with systhread support, though. The answer depends on what kind of GC and the quality of GC performance you require. If you are not concerned about the execution performance, it is not so difficult, say two-four weeks. If you need optimized performance, you need to modify the compiler because many GC strategies that can be accelerated by reducing the number of read/write barrier execution. If you are interested in modern GC strategies such as tag-free GC then you probably modify almost all part of O'Caml implementation.
