Comment (by rhaas):

 The patch looks ok with maybe the single exception that it does a VInfo
 from within the fork()ed child which may (or may not) involve transporting
 stdout data to the MPI root process? The suggested method of using a
 pthread might be safer in case there are still MPI implementations out
 there that do not like fork(). Maybe one could add a parameter to disable
 parallel writing. Otherwise fine to apply.
