Go 1.25 will gain support for overlapped IO on handles passed to os.NewFile thanks to CL 662236. It was previously not possible to add an overlapped handle to the Go runtime's IO completion port (IOCP), and now happens on the first call the an IO method. This means that there is code that relies on the fact that File.Fd returns a handle that can always be associated with a custom IOCP. That wouldn't be the case anymore, as a handle can only be associated with one IOCP at a time and it must be explicitly disassociated. To fix this breaking change, File.Fd will disassociate the handle from the Go runtime IOCP before returning it. It is then not necessary to defer the association until the first IO method is called, which was recently added in CL 661955 to support this same use case, but in a more complex and unreliable way. Updates #19098.
