True. However in the bounded-time GC space few projects share the same definitions of low-latency or real-time. So you have to find a language that meets all of your other desiderata and provides a GC that meets your timing requirements. Perc looks interesting, Metronome made similar promises about sub-ms latency. But I'd have to get over my JVM runtime phobia.

I consider one where human lifes depend on it, for good or worse depending on the side, real time enough.

Human lives often depend on processes that can afford to be quite slow. You can have a real time system requiring only sub-hour latency; the "realness" of a real-time deadline is quite distinct from the duration of that deadline.
