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: [<c0131210>] 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
