Log reopen broken in 2.2.33?

Has re-opening the logfiles broken between 2.2.32 and 2.2.33 releases?

Using the same config that I've had for the past 10 or so point releases, /usr/bin/doveadm log reopen works perfectly up until 2.2.32, but with 2.2.33 (and .1 and .2) no new logfiles are created, file descriptors still have the original files open and keep writings to those logs. On an idling test instance, I get:

master: Warning: Sent SIGKILL to 1 log processes

I can see both SIGUSR1 and SIGKILL generated by the master process, but the current log process doesn't terminate - it receives SIGUSR1, but not SIGKILL. Anyone able to verify this on their own setup? Am I missing a required config change? Using epoll, which hasn't changed.
