I've run into a problem with virtual functions and sip-4. The problem does not 
exist in sip-3.

I have a superclass with a (non-pure) virtual function, and a couple of 
subclasses that re-implement it. I create an object or two of the subclasses 
and register them with my C++ library through an exposed python method. My 
C++ code then calls the virtual functions, which are *not* reimplemented in 
python. 
The problem is that when sip_api_is_py_method is called, that thread stops 
when it tries to acquire the GIL. I have checked that don't have ANY calls 
from C++ into python via virtual methods (which is where another thread could 
have acquired the lock and not returned),

Where else should I look, and would this be some sort of a bug or another 
caveat for using C++ bindings?
