Releasing 3.5.3 even though technically this is an open release blocker.  IIUC the fix is checked in, and fixed the issue for OS X.  We don't know whether or not it is also fixed on OpenBSD, because we don't know anybody running OpenBSD, and nobody contacted us regarding OpenBSD during the 3.5.3 RC period.  Anyway I'm declaring victory and moving on.  Maybe we can mark this bug closed?
