Thanks for the reply, Henrik. Process Explorer still shows the file
handle as being open, but R only shows the following:
> showConnections(all=TRUE)
description class mode text isopen can read can write
0 "stdin" "terminal" "r" "text" "opened" "yes" "no"
1 "stdout" "terminal" "w" "text" "opened" "no" "yes"
2 "stderr" "terminal" "w" "text" "opened" "no" "yes"
