The subprocess module may suffer from a minor design flaw that is
described at http://unixwiz.net/techtips/remap-pipe-fds.html under the
heading "Descriptor Debacle". The problem can occur under rare
conditions when a subprocess is created from a Python daemon process.

Proposed solution:

Create a function os.duprange(*args) that takes one or more tuple pairs
of file descriptors. The function takes care of the necessary order and
dubbing of fds.
