The FieldStorage constructor calls the read_multi method.  The read_multi
method creates new FieldStorage objects, re-invoking the constructor

and 'strict_parsing' arguments originally passed to the constructor are not
propigated to the new object constructors.  This causes os.environ to be used,
leading to a miss-handling of the parts.

I fixed this by passing these arguments to read_multi and then on to the
constructor.  See the context diff below.
