Provided, you work under Linux, you can try to attach
to the process with GDB and analyse the thread behaviour.

I use the functions "ps" (Print String) and "pfr" (Print FRame)
during such analysis. They are defined by:

def ps
x/s ({PyStringObject}$arg0)->ob_sval
end

def pfr
ps f->f_code->co_filename
ps f->f_code->co_name
p f->f_lineno
end

You can apply "ps" to an string object.

You can call "pfr" in an "eval_frame" frame context.
