This fix to the MakeRequest() method gets rid of the hiddeous

exception message that shows up when a node goes into debug mode.  For
example, in the past one would see this type of message on the
console:

Exception exceptions.OSError: (2, 'No such file or directory', '/tmp/tmpBjmo14') in <bound method _TemporaryFileWrapper.__del__ of <closed file '<fdopen>', mode 'w+b' at 0xb7b108d8>> ignored

This is no longer the case.
