Detecting recursion loops

My code does recursion loops through a couple of functions. Due to problematic I/O input this leads sometimes to "endless" recursions and after expensive I/O to the Python recursion exception.
What would be a good method to detect recursion loops and stop it by user-Exception (after N passes or some complex criteria) without passing a recursion counter parameter through all the funcs?
