which means that bufa was incorrectly less than bufb, when they should have been equal.

In other words, something happened to let client A read stale data. :/

I haven't tried to figure out how that happened, or if it was something else — but by the memcmp man page that return code shouldn't be an error code or anything (98 is EADDRINUSE, if that matters?).
