I don't understand why do you think that this question should be posted in the Boost.Python mailing list.
"allow_threads" is just the code extracted from http://libtorrent.svn.sourceforge.net/viewvc/libtorrent/trunk/bindings/python/src/gil.hpp?revision=2460&view=markup ,
maybe a property like "adaptor" or "visitor" for each Py++ function would do the work, but I'm not so skilled with the Py++ API and probably there are other better solutions, btw something like: 

> tm = foo_class.mem_fun( 'test_method' )
> tm.adaptor = "my_adaptor"

and then Py++ will create:

> boost::python::class_< Foo >("Foo")
>    .def("test_method_1", my_adaptor(&Foo::test_method_1))

Another solution (probably more "clean") could be a list of Templates for each boost::python API (boost::python::class_::def, boost::python::class_::add_property ecc...) so that we can customize them, what about?

Thanks, that was useful! Btw I have to change the "whole template" and pay attention to keep it aligned in the next releases of Py++ (that's ok for the moment), what about adding $pre_call and $post_call params as in the "default" Template?

Thanks :)
