Hmmm... 21 is infinite? Interesting. I find that it would be interesting to me personally if the kernel was smart enough to spit out something like: Oct 15 16:24:38 larrylap kernel: [] find_[...]+0xa0/0xd0 [21 times] (of course, with find_usage_backwards spelled out) After all, what if it's practical that a specific recursion would run 3000 times and it gets caught at 5000 times? ("f**king bad design") Just a pet peeve of mine though. - -- We will enslave their women, eat their children and rape their cattle! -- Bosc, Evil alien overlord from the fifth dimension -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.3 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iQIVAwUBRTLMSgs1xW0HCTEFAQLvmQ/+I0ya8tRmqMjzYlqHSzOT7jBP0ExCrmQo elC3TYyfyGL6GJwlG9MdB5Fklf4DTB7p1Wn89+tua0VgfVJp7E045qCVeoyA/74u vAYaw2MHS/d2wacZN9SWXyqDvE6lnTbVnU1dQXoiSXYCu8mNQAgC0H2sW14e4qrL OJQdNTcJ9tV7gwoIbyuGFEP4iUQvNKBqShhtjBn10bvwuX4g+AKGkkbw0P43B2ss 9q6eoNEdfgNNQ+oCUlUr8UauuAkP633SL7Zym8AQ99KQLztne0PG6MfW5BAa6s+X 86hW8Y/6HEbqFJWMs8O3S2aUSnEqvzV/y5DirbdOynjDFi8OdWjMDr5XG4PFuGqP OhCenxfW+W7YTflHnqnB7Y0cQDvhFL9JrItaBDgfL/DkqF0ThiXjwbEYiid+wRRh 758AuYqlx6HYaHn2s1qqQSNRSuKSUj9YddvQknQgQtkq68vQsZ1v8qezwpJnmkKt 39jSUGV6s/1NHW3VOVrC/b2VThq7JT1qFG/LNuFpjHRs39gj/MK+vTZScHMJDTJe 0g9urF205RJPd2OgHsjhqRx0r+XaTUJtaJltpjcmC09jROTBYADWhGXP9m6lxaLE liQ3PiX1kePex0rWtH7dgaJMPJJKvUnLuW0w50TYoFY7R02sYseyWtxKLaU0vmaG w2P0InYQ00E= =YhSr -----END PGP SIGNATURE-----
