[PATCH 0/1] MR6339: reg/tests: Wait for TerminateProcess

[Anders Kjersem (＠anders)]

Tests can fail (seen on slow VMs) because `GetExitCodeProcess` is called before the child process is marked as terminated. `STILL_ACTIVE` is returned instead of the expected `1`.

dlls/kernel32/tests/loader.c#L3984 does a similar thing.
