Hi Stefan,

It is through ctypes.

True, I was using XSLT to auto generate the module. I will however explore this.

The code is used within plugin points and soon to be asynchronous code
(once  the original broken implementation is fixed) where in some cases it
will be instantiated 100's of 1000's of times etc...

Thanks,
