Load a module using the user mode module loader. The function returns
zero on success or a negative errno code on failure. Note that a
successful module load does not mean the module did not then unload
and exit on an error of its own. Callers must check that the service
they requested is now available not blindly invoke it.
</p><p>
If module auto-loading support is disabled then this function
becomes a no-operation.
