Dear Cordova developers and maintainers, This is ECNU3D from GitHub. I want to propose a potential improvement for the CDVCommandDelegateImpl.m. I filed a Github issue here: https://github.com/apache/cordova-ios/issues/452
My primary concern is that currently Cordova doesn't have any control about the concurrency of a plugin api call as we're using global dispatch queue directly(application may easily reach the GCD global thread limitation if developer abused async function like promise). I think as iOS has already provided the more advanced NSOperationQueue utility, why not we consider to replace the dispatch queue with it? Have a limitation and control on number of concurrency of plugin calls from the Cordova side will bring a lot of benefits and make the app more stable even the app developer abused the plugin api call(call it with promise.all for 1000 times.). I also created a PR to demonstrate this idea: https://github.com/apache/cordova-ios/pull/454 I'm just a newbie of Cordova development, and input or feedback is largely welcomed. BR, ECNU3D
