[erlang-questions] Re: Chain two spawned processes

[Max Lapshin]

Yes, it seems, just that Erlang unix layer lacks all these process
control stuff.

Look, what I really need is to connect two processes via one pipe so
that no data is passed through beam,
and grab stderr of second one to controll process of execution.

sys.c cannot do this right now.

Currently I will do exactly as You say: launch shell script. However,
maybe will be reasonable to make patches to erlang unix/sys.c
to add more control for process starting and spawning?
