[R-SIG-Mac] What are these other 'R' processes?

[Carl Witthoft]

  "I Never Looked"  category!  I was checking the Activity Monitor and 
noticed that, in addition to a process called "R" which displays the R 
logo , I have six other processes called "R" with just a plain capital "R" .
These others all have newer PIDs than the "main" R.  One of them appears 
to be idling with a bit of CPU usage while all others, including the 
'main' one, are at zero CPU (I'm using Rgui.app and at the moment not 
running any command).

Do these other processes matter? Are they leftovers?

thanks
Carl
