  Try to get this test to be less flaky.  It was failing sometimes because
  the connect would succeed before the timeout occurred.  Try using an
  address and port that hopefully doesn't exist to ensure we get no response.
  If this doesn't work, we can use a public address close to python.org
  and hopefully that address never gets taken.

  Ensure that the mailbox is closed to prevent problems on Windows with removing
  an open file.  This doesn't seem to be a problem in 2.6, but that appears
  to be somewhat accidental (specific to reference counting).  When this
  gets merged to 3.0, it will make the 3.0 code simpler.

+        'b' - Binary. Outputs the number in base 2.
+        'c' - Character. Converts the integer to the corresponding
+              Unicode character before printing.
+        'd' - Decimal Integer. Outputs the number in base 10.
+        'o' - Octal format. Outputs the number in base 8.
+        'x' - Hex format. Outputs the number in base 16, using lower-
+              case letters for the digits above 9.
+        'e' - Exponent notation. Prints the number in scientific
+              notation using the letter 'e' to indicate the exponent.
+        'g' - General format. This prints the number as a fixed-point
+              number, unless the number is too large, in which case
+              it switches to 'e' exponent notation.
+        'n' - Number. This is the same as 'g', except that it uses the
+              current locale setting to insert the appropriate
+              number separator characters.
