The tool wlmscpfs (and underlying library) should also work without a "lockfile" in the respective worklist files directory. Currently, an error is reported and the tool refuses to work if no "lockfile" is found when a request is processed.

In order to be backward compatible, this could be implemented by the following new options:

--auto-lockfile    = check whether there is a lockfile and use it if present during application start (default)
--disable-lockfile = don't check for a lockfile and don't use even if it is present
--enable-lockfile  = check for a lockfile and always use it (fail if absent)

The old behavior could be selected by the --enable-lockfile option. This could still be useful when creating or modifying worklist files while the SCP is running. Of course, the --auto-lockfile option (default) would then also work.
