Hi,

since the 3.8.0b2 test_asyncio freezes in test_subprocess when MultiLoopChildWatcher is being used as a watcher (new in b2). All other watchers are working as expected. This is all on Solaris.

I tried to find out the reason for these issues and it seems that awaited coroutines never end (there are many tests with this problem - I tested it on test_cancel_make_subprocess_transport_exec). I found out that commenting out `signal.siginterrupt(signal.SIGCHLD, False)` in `attach_loop` method of MultiLoopChildWatcher seems to fix the issue, however, I don't understand this enough to see why that should be a problem...

I can provide more information if necessary.
