[Rd] Background session with R

[Gábor Csárdi]

You might find the https://github.com/r-lib/processx package useful.

Also, the dev version of https://github.com/r-lib/callr might be
useful. (The CRAN version of callr does not support background
processes.)

I am aware that "parallel" does a lot of that - however, "parallel" shuts down the nodes when I quit the master process. On the contrary, I would want these nodes to continue running, so I can fire up R again later and reconnect to the nodes to retrieve the results.
