I would almost always make a type if the exception can be handled by

You
r reclaim it.
Since it's the Scheme stack and I suppose it's tail call optimized, that
should not impact the GC.
The most important thing would be to check the memory usage of the
program with a tool like `htop'. If there's leak, you will see that the
memory usage percentage keep increasing.
