+    posix/tst-spawn: Fix racy tests in spawned processes.
+    
+    From time to time I get fails in tst-spawn like:
+    tst-spawn.c:111: numeric comparison failure
+       left: 0 (0x0); from: xlseek (fd2, 0, SEEK_CUR)
+      right: 28 (0x1c); from: strlen (fd2string)
+    error: 1 test failures
+    tst-spawn.c:252: numeric comparison failure
+       left: 1 (0x1); from: WEXITSTATUS (status)
+      right: 0 (0x0); from: 0
+    error: 1 test failures
+    
+    It turned out, that a child process is testing it's open file descriptors
+    with e.g. a sequence of testing the current position, setting the position
+    to zero and reading a specific amount of bytes.
+    
+    Unfortunately starting with commit 2a69f853c03034c2e383e0f9c35b5402ce8b5473
+    the test is spawning a second child process which is sharing some of the
+    file descriptors.  If the test sequence as mentioned above is running in parallel
+    it leads to test failures.
+    
+    As the second call of posix_spawn shall test a NULL pid argument,
+    this patch is just moving the waitpid of the first child
+    before the posix_spawn of the second child.
+    
+    ChangeLog:
+    
+            * posix/tst-spawn do_test(): Move waitpid before posix_spawn.
