....

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.
