Tomas Mraz 64d7688acb Do not fail locking if there is a stale lockfile.
As the lockfiles have PID in the name, there can be no conflict
in the name with other process, so there is no point in using
O_EXCL and it only can fail if there is a stale lockfile from
previous execution that crashed for some reason.
