29 # its become 5. Who knows what it might be next.
30 # Note2: On IRIX, the limit is around the 30 mark.
32 # What we are looking for here is: no panic due to blowing the stack;
33 # and that the ELOOP error code is returned at some point (the actual
34 # limit point is unimportant, just checking that we do hit it).
