def monkey_patch(**on):
    """Globally patches certain system modules to be greenthread-friendly.

    The keyword arguments afford some control over which modules are patched.
    If no keyword arguments are supplied, all possible modules are patched.
    If keywords are set to True, only the specified modules are patched.  E.g.,
    ``monkey_patch(socket=True, select=True)`` patches only the select and 
    socket modules.  Most arguments patch the single module of the same name
