// where "message" is the replyobj function that will be called
// with the string as its single argument.  The replyobj function
// is not executed immediately, but rather is executed in the main
// python thread by the interpreter "at the earliest convenience".
// This means the calling C++ function will run to completion
// before the replyobj function is called.
//
// This function is mainly intended to report errors from functions
// where throwing an exception is not practical (e.g., when rendering
// graphics).  It is also useful for logging informational messages
// such as computed values without having to modify the Python layer.
