Do you have any links to reading material on this type of GC?

That's exactly what we're talking about, but we do the work that
was done by the globalisation policy by using the `new shared`
keyword. We end up with a language that support the very
foundation of what I'd say is the most solid Garbage Collection
model.
"To summarise these results, it seems that
although the local heap collector performs many fewer
young-
generation collections and fewer synchronisations, the benefits
are
offset to some extent by the extra work being done by
the col-
lector to maintain the global-heap invariant. "
"Globalising the entire transitive closure was on average
93%
slower, and results ranged from 7% faster to 577% slower."
"A garbage collector with local per-processor heaps can outperform
a stop-the-world parallel garbage collector in raw parallel
through-
put, and exhibits more robust performance through having fewer
all-core synchronisations. "
