-// On Windows, any process can create an IPC channel and others can fetch
-// it by name.  We pass around the channel names over IPC.
-// On POSIX, we instead pass around handles to channel endpoints via IPC.
-// When it's time to IPC a new channel endpoint around, we send both the
-// channel name as well as a base::FileDescriptor, which is itself a special
-// type that knows how to copy a socket endpoint over IPC.
-//
-// In sum, when passing a handle to a channel over IPC, use this data structure
-// to work on both Windows and POSIX.
