/* Convenient conversion routines for C<->Python data interchange
   
   Note that all of these routines assume that we have the global
   interpreter lock - blocking all other threads.
   
   There are three ways to get it:
   
   - call PBlock() [followe by PUnblock() when done]
   
   - call PBlockAndUnlockAPI - [followed by PLockAPIAndUnblock() when
   done]
   
   - or in response to a call to the PM API, you will have the main
   Python thread by default.  [Note that within an
   APIEntry(),APIExit() block the lock is released, so these
   functions should be called outside of that block].
