Comment (by simoncperkins@…):

 As I have pointed our in the past, I think there are some issues with the
 implementation on Windows. One issue is that it passes a
 lpNumberOfBytesRevd/Sent to WSASend/WSARecv even though the docs state:

 '''Use NULL for this parameter if the lpOverlapped parameter is not NULL
 to avoid potentially erroneous results. This parameter can be NULL only if
 the lpOverlapped parameter is not NULL.'''

 Also, I believe there is a potential efficiency issue due to the overuse
 of PostQueuedCompletionStatus.

 See this ticket for more information:

 We are running with the patch in that ticket applied to boost 1.55
