Is netdb_lock the GIL?
If the thread pooling was effective, the slowdown wouldn't be linear, but it
does i

As far as our experiments show, the requests are blocking each other
irrespective of thread pool size. Which is expected since the lock is global
across threads.
Am I correct in assuming that an implementation for the ProactorEventLoop with
IOCP would

would be nice to have their corresponding methods in asyncio.ProactorEventLoop
use IOCP, so that they wouldn't block the whole event loop.
Overlapped I/O flags are avai
