pg_ctl timed out waiting for the zombie postgres.

stop -D /maumau/postgresql-9.4/src/test/regress/./tmp_check/data -s -m fast

pg_regress must wait for postgres to terminate by calling waitpid(), because
it invoked postgres directly. The attached pg_regress_pg_stop.patch does
this. If you like the combination of this and the original fix for pg_ctl
in one patch, please use pg_stop_fail_v3.patch.

Sorry for causing trouble.
