ParallelBackupStart() stored _beginthreadex()'s return value as the worker's thread handle without checking it. On failure that value is 0, which would later reach WaitForMultipleObjects() as a null handle, caught only by an Assert. The fork() path already calls pg_fatal() when it fails; do the same for _beginthreadex(), as pgbench does.
