Review Comment:
@szetszwo Thanks for pointing this out! I agree that this test should
preserve the async write-then-read-after-write ordering; calling get() between
the two async calls would make the test ineffective for the intended
read-after-write semantics.
Given that `RATIS-1931_grpc-zero-copy` is currently far behind master, and
this area may already have been fixed or moved to LinearizableReadTests on
master, I agree the better next step is to merge/rebase from master first.
After syncing the branch, I will re-check whether the issue still exists before
making any local test changes.
