\modulesynopsis{Drop-in replacement for the \refmodule{thread} module.}
This module provides a duplicate interface to the \refmodule{thread}
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 thread as _thread
except ImportError:
    import dummy_thread as _thread
\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.
