Check out:

"When klogd's LogLine() function encounters a null byte in state
PARSING_TEXT, it will loop infinitely. More precisely, copyin()
will treat the null byte as a delimiter - unlike LogLine(), which
will invoke copyin() ever and ever again."

Kinda off-topic, but I just wanted to prove that the bug was in klogd and
not the kernel. :)
