Would it be horribly expensive to generate a better runtime error, or even initialize the gil on demand? If the gil is not initialized, get the thread ID of the thread calling the callback and check against the thread entering at module initialization time...I don't know whether pythread.h has a cheap way of achieving this. -- Sent from my Android phone with K-9 Mail.

I don't really like this either. The reason why the GIL is not being initialised by default is that it has a runtime impact. Just because code is aware of threading does not mean it is going to be used with threads. Especially library code (which is a common place for using Cython) shouldn't impose such an impact on the rest of the runtime.
