Thats ... just wacko. do_stop() emits "waiting for server to shut
down...", "done", and "server stopped" in the same way (via print_msg).
How is it that all three messages show up in one context but not the
other? Could wait_for_postmaster_stop or get_pgpid be bollixing the
stdout channel somehow? Try redirecting stdout and stderr separately
to see if that proves anything.

Indeed, that's even weirder. do_stop() returns directly to the
exit(0) in main().
