 // There are two channel creation APIs: |CreateChannelOnIOThread()| creates a
 // channel synchronously and must be called from the I/O thread, while
 // |CreateChannel()| is asynchronous and may be called from any thread.
 // |DestroyChannel()| is used to destroy the channel in either case and may be

 // thread.

 // Both creation functions have a |platform_handle| argument, which should be an
 // OS-dependent handle to one side of a suitable bidirectional OS "pipe" (e.g.,
-// a file descriptor to a socket on POSIX, a handle to a named pipe on Windows);
-// this "pipe" should be connected and ready for operation (e.g., to be written

 // This message pipe may be used immediately, but since channel operation
 // actually begins asynchronously, other errors may still occur (e.g., if the

 // returned handle.
