Request: add count to "[warn] Your computer is too slow..."

Seen with Tor v0.2.2.35:

"[warn] Your computer is too slow to handle this many circuit creation requests! Please consider using the MaxAdvertisedBandwidth config option or choosing a more restricted exit policy."

It would be helpful if the number of connections that occasion this warning be stated in the message. I suggest replacing the text "this many" with an actual number.

Thanks.
