Nope, as that's the fastest path we have to shut down any remaining
nodes at the end of a test per the END{} block at the end of
PostgresNode.pm, and I would rather keep it this way because people
tend to like keeping around a lot of clusters alive at the end of any
new test added and shutdown checkpoints are not free either even if
fsync is enforced to off in the tests.
I think that a solution turning around __gcov_flush() could be the
best deal we have, as discussed last year in the thread Álvaro quoted
upthread, and I would vote for waiting until v14 opens for business
before merging something we consider worth it.
