Yes that's right. I had a look at the code too and finally understood the "set_finalizer" part of the documentation. And this is exactly what I need.
So I simply added a desinit method to my module, a finalizer to my lane that calls it, some sanity check code in the desinit/gc implementation to avoid to perform desinits more than once or from the wrong thread, and all is fine now.

Problem solved :-)
