Still outputs "Rserve started in non-daemon mode." for each request (#23)

[malcook]

I find that #23 is still an issue. Below is my attempt to provide a reproducible example based on using more recent versions of R and Rserve.

The attached RserveIssue.sh.txt is a bash script which puts an undaemonized Rserve process into the background using nohup, logging its output. It then sends it a few expressions to evaluate.

It can be run as:

$ bash < RserveIssue.sh.txt

The server's log produced demonstrates how "Rserve started in non-daemon mode." is emitted multiple times:

nohup: ignoring input
