The finishGEOS_r function is supposedly called when the user is no longer
willing to use a specific "context". The finishGEOS function is supposedly
called when the user is no longer willing to use the library, until next
call to initGEOS. That's how they are documented.

One way to track created geometries would be putting them in a list on
creation and dropping them off the list when destructed (there's a C-API
endpoint for deleting them). But some geometries are created "internally",
as the result of operations. Those geometries would be harder to get on 
that list.

Would such tracking list be worth it ? Or better to just document the
problem and let the user be able to shoot their feet ?
