[minggo]

it is because websocket is using multi-thread, when you close the app, it is waiting another thread.

[dumganhar]

Please refer to #17369
BTW, bsd socket on iOS have lots of issues hard to be fixed. We're trying to use SRWebSocket which is based on CFNetwork for iOS & macOS platforms.

i fink it is bad design. Шt will crash on all desktop platforms that have close button. I think there is no need to lister dispatcher reset because on program close all sockets will be closed.
