I think Nim author need to documentate/explain/illustrate a lot more about its GC. I once have interested in Nim, but I couldn't figure out how its GC is proper (predictable & deterministic rather than throughput) to RT apps. And that dropped my interest on it. I believe this is a biggest obstacle to RT app programmers to take interest on Nim.

Nowadays the term "GC" almost implies "tracing GC", so "non-tracing GC" need to be well explained. Or need to adapt some new term to explain new concept. Currently, Nim's GC explanation just looks like incremental RTGC that is not really attractive to existing RT app programmers.

Have you taken a look at the GC documentation (http://nim-lang.org/gc.html)?
