Stdin handling for terminals is broken on Windows #302
Description
I just created a simple tasks file on Windows:
from invoke import task, run
@task
def foo():
print("Hello, world!")
run("echo Hi")
When I try to run it (invoke 0.12.0, Python 3.5.0 64-bit) on Windows 7, I get the following error:
>inv foo
Hello, world!
Hi

Note that the task output appears fine, so it's not clear what's going on here. Is it possible that invoke is trying to use select.select on sys.stdin? That's not allowed on Windows, you can only use select on sockets...
