That's true, though you still need the thread ID for references to

I am not really sure how useful references to gc-pointers is. I
certainly would trade them in for multiple return values. I also think
it is reasonable to ban transfer of GC mem to C code if all GC mem is
accounted for with gc-typed pointers...
I think the GC is the future of D considering it's embedded to the very
core of the language, and compatibility with C code is ... elementary.
Also, thread IDs in ptr references are to the GC as ref counts are to
the smart pointers. If you remove the refCount from smart pointers, you
end up scanning the whole memory to count them don't you? So then, why
remove the thread ID from GC references, if only to look for them in
each thread? You slow the GC down by as much total memory there is in
all threads vs the avg in a thread, AND you remove parallel collection -
by not having the Thread ID in gc ptr references
So you understand that's exactly why the GC has to stop the world, and
no gaming platform will ever turn to the default behavior of a language
if it stops its world. As a matter of fact, I can't see any other way of
fixing the GC than adding the Thread ID in there :/
