The doc says

	// Unlike io.Writer.Write, Endpoint.Write transfers ownership of any bytes
	// successfully written to the Endpoint. That is, if a call to
	// Write(SlicePayload{data}) returns (n, err), it may retain data[:n], and
	// the caller should not use data[:n] after Write returns.

but the signature of Write has since changed. It no longer accepts a slice payload, so this advice is no longer applicable.

For posterity the comment in question is here:

gvisor/pkg/tcpip/tcpip.go

Lines 506 to 509 in b8b43f7

// Unlike io.Writer.Write, Endpoint.Write transfers ownership of any bytes
// successfully written to the Endpoint. That is, if a call to
// Write(SlicePayload{data}) returns (n, err), it may retain data[:n], and
