@paoloredaelli @clacke also, it has competition - the ZGC collector developed by Oracle, and Shenandoah by Red Hat; the details differ, but they all use some combination of concurrent tracing and copying and reference load barriers

i guess all the fun GC development seems to be happening in Java with massive heaps, because Java is the most widely used GC'd system, and also the one used in the largest installations; that's a shame, because there are peculiarities to the Java environment (finalisation, universal synchronisation, unboxed values by default) that may not apply to other platforms (eg Lisp, Smalltalk)

really i wish people would start doing serious work on GCs for tiny heaps (eg 16-bit addressable) rather than going "oh, naive mark & sweep can collect the whole heap in 2ms, Our Work Here Is Done™"
