Some further tweaks to reduce fragmentation when allocating the
nursery
commit 1f5d83648dfda39d999eb8a9e8192339b3eea540

Allow allocNursery() to allocate single blocks (#7257)
Forcing large allocations here can creates serious fragmentation in
some cases, and since the large allocations are only a small
optimisation we should allow the nursery to hoover up small blocks
before allocating large chunks.
commit c19f2e320a575a66d31c83d846ce3cc954c4ab3b

Include pinned memory in the stats for allocated memory
This broke with the changes to the pinned object handling in
67f4ab7e6b7705a9d617c6109a8c5434ede13cae.
