Ok, a more accurate description would be:

When I do M-x R it hangs for a bit. At this point, nothing has any effect
except Ctrl G, the menus don't respond etc. After a couple of minutes R
does start up in a second buffer, and the minibuffer says

Timeout waiting for prompt. Check inferior-ess-prompt or ess-loop-timeout.
