That's because SIP has never supported the cyclic garbage collector. That is 
now fixed and your test script shows no leak.

I've also added %GCTraverseCode and %GCClearCode to allow classes that include 
references to Python objects to play nicely. The only example in PyQt is 
QCustomEvent.

Thanks for all the testing you've been doing recently - it's been really 
useful.
