It's not about using an IDE, it's the more complex and delicate control
flow that asynchronous IO (IOCP / Overlapped) imposes compared to
non-blocking IO (e.g. select()).

Not to mention that lifetime issues are hard to handle safely and
generically before Vista (that is, before CancelIOEx():
s.85%29.aspx -- "The CancelIoEx function allows you to cancel requests
in threads other than the calling thread. The CancelIo function only
cancels requests in the same thread that called the CancelIo function")
