As an example from a bit different area, in Chrome the Web Workers today require a separate process per worker. It's not good to create too many processes so there is a relatively low limit per origin and higher total limit. Two limits help avoid situation when 1 bad page affects others. Once limit is reached, the worker objects are created but queued, on a theory that pages of the same origin could cooperate, while if a total limit is blown then hopefully it's a temporary condition. Not ideal but if there should be a limit we thought having 2 limits (origin/total) is better then have only a total one.<div>

</div>Ah. Thats a good question. (Maybe that was the original question.)<br>
<br>
Since web sockets is the topic and as far as I know web sockets are only used by javascript, I would prefer an error over queuing them up.<br>
<br>
I think javascript and browser facilities have what is needed to create its own retry mechanism if that is what a particular situation wants. I don't see driving the retry via a scripting language to be bad. Its not that hard and it won't happen that often. And it gives the javascript authors more control and choices.<br>
<br>
Thats my vote...<br>
