v5 attached. cfbot failed 058_syncrep_release on both Windows tasks:
# die: SIGCONT walsender: Invalid argument at
.../058_syncrep_release.pl line 92.
Both scenarios in that test hold a process with SIGSTOP/SIGCONT, which
Windows doesn't have. 0003 now skips the test there, the same way
019_replslot_limit.pl and 038_walsnd_shutdown_timeout.pl skip their
kill-based parts. Nothing else changed.

Vadim Ponomarev
