-// On Windows we access pipes in various processes by name.
-// On POSIX we pass file descriptors to child processes and assign names to them
-// in a lookup table.
-// In general on POSIX we do not use unix domain sockets due to security
-// concerns and the fact that they can leave garbage around the file system
-// (MacOS does not support abstract named unix domain sockets).
-// You can use unix domain sockets if you like on POSIX by constructing the
-// the channel with the mode set to one of the NAMED modes. NAMED modes are
-// currently used by automation and service processes.
+// Channels are implemented using mojo message pipes on all platforms other
