I remember getting one a 0 byte in the middle of the filename on
a SYSV filesystem (fixed length names).
Was impossible to get a match, probably because the kernel was matching
all the bytes.
Probably happened due to a randmon kernel overwrite getting paged out.
(We would have been testing device drivers on that system.)
