But on Nov. 5, 2003, Larry McVoy
noticed
that there was a code change in the CVS copy that did not have a
pointer to a record of approval. Investigation showed that the change
had never been approved and, stranger yet, that this change did not
appear in the primary BitKeeper repository at all. Further
investigation determined that someone had apparently broken in
(electronically) to the CVS server and inserted this change. What did the change do? This is where it gets really interesting.
The change modified the code of a Linux function called wait4, which a
program could use to wait for something to happen.
