 message_queue is using the TMP environment variable to determine where to
 put the file that implements a shared memory object (on Windows and Mac OS
 X).  The TMP environment variable gives different paths for different
 users under Windows and Mac OS X.  Also, there are permission problems
 that wont allow a queue created by a windows service (or daemon on Mac) to
 be read from / written to by a user mode process (see ticket #1080).  This
 makes the message queue unusable for a fairly typical use case.

 Suggested fix: create a new message_queue constructor that takes as
 parameters a file path to be used as a shared memory object and what kind
 of permissions this file should have.
