Now as to when, well, I'm waiting for your PR.
They will never have the performance of e.g, jemalloc.
In fact I will. The design of SDC's GC is based on jemalloc after
extensive discussion with Jason Evan. He is considering
backporting part of the work in jemalloc.
Namely, the only major additional work that need to be done is to
write one uint per page on "large" allocations (namely 16kb -
192kb) in order to be able to detect internal pointers.
Considering these aren't that common to boot, this is not
expected to impact perfs significantly.
On the other hand, D's type system can be leveraged to reduce
lock contention on the GC (and not lock at all on thread local
allocs).
Really, there is a lot to be done here and I'm reluctant to push
for more language things while what we have is far from top notch.
