Re: sage-devel thread: I was wondering what you were waiting for.
(Haven't tested the patch here; I think you won't be able to print PARI's
variables with this method anyway, at least not easily.)
Note that you can inject code into the C files generated by Cython, e.g.
with your favourite friend `sed`, especially into the functions called
upon module initialization:
{{{
#!sh
$ cd devel/sage/sage/rings
$ sed -i -e '/^PyMODINIT_FUNC PyInit_.*(void)$/,+3s/^{$/{\n
printf("Hello!\\n");\n/' real_mpfr.c
$ ../../../../sage -br

Hello!

(This example is of course quite specific to the current layout of the C
code generated by Cython. Also, for simplicity I've used the less portable
`-i` option.)
Just a "proof of concept"; I can write an appropriate shell script for
your debugging purpose once I've found the relevant ticket... ;-)
