Whatever the benefits of the other pieces of information sending the
process command line is absolutely wrong.  It is a just a random string
from user space and there is absolutely no benefit in sending it in a
kernel verified way.  The process can just as easily pass the
information in userspace directly.

Furthermore the implementation of scm_get_current_procinfo is so far
from idiomatic for reading information about the current process that I
think it is fair to call it broken.
