I know this isn't about mod_python, but I can think of nobody better qualified to answer this question than mod_python developers.
If in a C function you release the GIl using begin/end allow threads, does it change your responsibilites with regard to the reference counts on the input parameters? unsigned char * str; int len; PyArg_Parse(args, "s#", &str, &len) Now if you do a Py_BEGIN_ALLOW_THREADS, and do something time consuming without any python calls, can you count on str not being deallocated somehow while you work?
