Improving perf of FileChannel.transferTo() on Windows

[Kirk Shoop (MS OPEN TECH)]

From: Valery Kopylov (Akvelon)

Issue 2: transferTo() is now working only synchronously.
Solution: We could always open socket with WSA_FLAG_OVERLAPPED option - it does not make all socket operations asynchronous by default, just allows that. Then transferTo() is called in overlapping mode or not, depending on socket mode that has been selected in configureBlocking().
How would the Java code calling transferTo be notified that the transferTo had completed?
