Feature: Async IO?

It doesn't look like to me that there is any support within Pwntools for asynchronous IO (for example, being able to start 100 remote processes and deal with them at the same time, rather that one after the other). Since there is also no Python 3 support, the only way I can see this being done is through python modules like `threading` or `multiprocessing`. Just wondering, has this ever been considered for development or is there an easy way this can be achieved?
