+PH/19 When an Exim process that is running as root has to create an Exim log
+      file, it does so in a subprocess that runs as exim:exim so as to get the
+      ownership right at creation (otherwise, other Exim processes might see
+      the file with the wrong ownership). There was no test for failure of this
+      fork() call, which would lead to the process getting stuck as it waited
+      for a non-existent subprocess. Forks do occasionally fail when resources
+      run out. I reviewed all the other calls to fork(); they all seem to check
+      for failure.
