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