Hmm.. so in an effort to check to ensure things were thread safe, I've
put in a bunch of thread blocking stuff. Around all code that calls to
python, I call Py_BLOCK_THREADS and Py_UNBLOCK_THREADS. The problem
this yields is that when it hits the PyQt stuff, it hangs, trying to get
I guess I'm wondering if I'm doing something dramtically wrong here?
Basically, what I have now is, in my constructor, I call:
_interp = PyInterpreterState_New( );
_save = PyThreadState_New(_interp);
At the end of it, I call Py_UNBLOCK_THREADS
Then, I wrap all Python calling code as stated above. Suggestions?
