No. If the current buffer has no association, eldoc asks first available
process (if any). To check if the buffer is associated with a process,
you should consult `ess-local-process-name` variable.

Asked when? ESS naturally asks that when execute the code from that
script, but eldoc should not ask. I cannot reproduce this and I have no
idea how that could happen unless you have some custom completion code
that pings R process behind your back.
