Ah OK and thanks. I had not realised it worked this way but it makes sense. This
limits what SYSINT offers over constructors but SYSINIT is a much better means
of specifying and performing these initialisation operations. There is no
sequencing in constructors.

Yes so it can use any RTEMS resource.
