Thanks for doing the experiments. I plan to implement a method in the 
SIP Python module that will provide direct access to the C++ dtor for 
the rare cases (of which this is probably the only one in PyQt) where 
the API being wrapped is lacking.

The reason that I haven't done it yet is that the SIP module will be 
renamed in the "near" future from "libsip" to "sip", so if I add methods 
now I will soon be breaking them.

Would you prefer to see libsip.sipCallDtor() in SIP v3.3 or can you wait 
for sip.sipCallDtor() in SIP v4.0?
