Append wait time or rate for every thread due to server limits

[latot]

Hi, actually some server has some limits, is hard to tell a server too much requests and in some ones the rate can be very low.

I think would be great be able to set a strategy to be able to handle this, some ideas:

• Set a rate of request per second
• wait some time after complete a request

I think would be pretty useful implement something like this.

Thx!

I think this would be a very useful feature. I've looked at some existing implementations of rate-limiting and I was a bit overwhelmed by the number of different ways rate-limiting can be implemented.

It's not clear to me if any one rate limiting strategy stands out as more useful in the context of grequests than others. I suppose the rate limiting a user would want grequests to use depends on how the server implements rate limiting.

In any case, I'd like to figure this out and get it implemented.
