# 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).
