Indeed, there is no special thread.

I'd say for the more relaxed reddit audience it can be put like 
this: the GC isn't "running" at all. Not persistently, not at all 
times, not in any special thread. It is not actively scanning 
anything. Any allocation on GC heap made by *any* thread *may* 
cause a collection, which is performed there and then in the same 
thread that triggered said allocation, and is observed as part of 
that allocation. All registered threads except the one that 
triggered the allocation (and thus, collection) are paused for 
scanning and resumed afterwards. Threads not registered with the 
runtime or those that were explicitly detached from the runtime 
are expected to not hold any pointers to the GC heap, and are 
neither paused nor scanned.
