def copy_current_request_context(f):

    ''''A helper function that decorates a function to retain the current
    request context.  This is useful when working with greenlets.  The moment
    the function is decorated a copy of the request context is created and
    then pushed when the function is called.
    Example::
    import gevent
    from flask import copy_current_request_context
    @app.route(\'/\')
    def index():
    @copy_current_request_context
    def do_some_work():
    # do some work here, it can access flask.request like you
    # would otherwise in the view function.
    gevent.spawn(do_some_work)
    return \'Regular response\'
