 It seems that it is in many cases not safe to call fork() in MPI
 applications. This page <http://www.open-mpi.de/faq/?category=openfabrics
 #ofa-fork> has some information. The upshot seems to be:
 - In many (most) cases, one can call system() or popen() to execute
 external processes while waiting for them.
 - It is generally not safe to call fork() to execute a certain task in the
 background. However, it should be possible to use threads in this case.
