How hard would it be to modify D's GC to do the following two

1. Scan the heap in the BG on another thread/cpu for
compactification.
needs read/write barriers added to generated code. a major

ALL memory access.
Only modifications of pointers, which introduce new cross-block
dependencies (so that GC knows to recheck the new dependency).
Other memory access goes without slowdown.
