Hi,

I'm using this tool as part of our development-pipeline running gulp. We are using pageres as part of our daily development on our local machines when developing static html-websites. There exists a task where we can create screenshots with given resolutions for all of our created html-files.

Is it possible to reduce the processes which are spawn to have a given limit?

It is already mentioned, that the mutiple processes are concurrent, but having a lot of resolutions (at least 10 sometimes for each page) creates a big memory- and process-increase which slows down the development-system by making it less responsive while phantomjs-processes are created/executed.

As workaround we were creating a new instance of pageres inside the .then() via callback, often resulting in warnings about "SIGINT listeners above 11" which seems not to work on our continuous-integration server.

Is there a nice way to take a screenshot of a lot websites (at least 10) with a lot of resolutions (at least 5 to 10) without having all processes created at the same time? How to create a nice queue for this?
