I have several qustions about processes:

1)  How can I get a name of a process? The standard proc_$get_info
    doesn't return any information about the name of process. Is the
    4 byte long UID related to any text string(name of the process)?
    Also is there a call to name the process itself, like some of the
    server programs (spm server, mbx_server) do?

2)  Is there any SID (user.project.org.node) related to a process and
    can be accessed? 

3)  Are there any standard calls equivalent to /com/ppri and /com/sigp
    available?

4)  Is there any kind of ownership of a process? Or at least some
    kind of protection scheme to protect a process being killed by
    inappropriated user. In VMS, you can setup a process so that other
    users without privilege can't change its priority or stop the
    process. I would like to see something similar implemented in
    Aegis. The protection scheme would be:

    a) Only the owner of a process can modify its priority (/com/ppri)
       or stop it(/com/sigp), or
    b) %.sys_admin and %.locksmith can perform the same.
    c) a option to make a process without protection (open process)
       if desired.
