Suggestion: specify that all systems either have an argv[0] at the
beginning, or that all do not.  In the case that there is no natural
argv[0], the implementation should provide one with an unspecified
value.  That said, implementations shout prefer to use the name of the
file containing the main program.

Both are useful.  This one should probably be wall-clock time.

Example:

    scheme@(guile-user)> (get-internal-r
    get-internal-real-time  get-internal-run-time   
    scheme@(guile-user)> (get-internal-run-time)
    $1 = 117657808
    scheme@(guile-user)> (get-internal-real-time)
    $2 = 15237676615
    scheme@(guile-user)> internal-time-units-per-second
    $3 = 1000000000

I don't suggest the name "real-time", it's confusing I think.
