\section{\module{dummy_threading} ---         Drop-in replacement for the \module{threading} module} \declaremodule[dummythreading]{standard}{dummy_threading}\modulesynopsis{Drop-in replacement for the \refmodule{threading} module.} This module provides a duplicate interface to the\refmodule{threading} module.  It is meant to be imported when the\refmodule{thread} module is not provided on a platform. Suggested usage is: \begin{verbatim}try:    import threading as _threadingexcept ImportError:    import dummy_threading as _threading\end{verbatim} Be careful to not use this module where deadlock might occur from a thread being created that blocks waiting for another thread to be created.  This often occurs with blocking I/O.
