26 # Note1: On Linux, ELOOP limit used to be 32 but changed to 8, and lately
27 # its become 5. Who knows what it might be next.
28 # Note2: On IRIX, the limit is around the 30 mark.
30 # What we are looking for here is: no panic due to blowing the stack;
31 # and that the ELOOP error code is returned at some point (the actual
32 # limit point is unimportant, just checking that we do hit it).
