Not perfect, but I get something (at first glance) usable with:
main(_) -> shell:server(false, false).
Haven't tested it for more than ten seconds, but that can turn into a
rpc:call(, shell, server, [false, false]).
I'm not absolutely sure, but I think that when you run this:
$ escript ./foo arg1 arg2
…what essentially gets executed is this:
$ erl +B -noshell -s escript -- ./foo arg1 arg2
And I wonder if the -noshell switch does something other than just not
starting a shell? Something that will make it impossible to get a 100%
