I got around to testing this on a 25 node cluster and fixed a small
remaining problem. Looks good to me now.
Although it uses more coarse-grained locking than the current master, the
performance did not suffer in comparison. We should improve it when it becomes
a problem.
The connections are reliably closed after the idle timeout and the debug
logs indicate that they have also been closed/opened during execution jobs
without problems.
