-// This is used to create a pair of |PlatformHandle|s that are connected by a
-// suitable (platform-specific) bidirectional "pipe" (e.g., socket on POSIX,
-// named pipe on Windows). The resulting handles can then be used in the same
-// process (e.g., in tests) or between processes. (The "server" handle is the
-// one that will be used in the process that created the pair, whereas the
-// "client" handle is the one that will be used in a different process.)
-//
-// This class provides facilities for passing the client handle to a child
-// process. The parent should call |PrepareToPassClientHandlelToChildProcess()|
-// to get the data needed to do this, spawn the child using that data, and then
-// call |ChildProcessLaunched()|. Note that on Windows this facility (will) only
-// work on Vista and later (TODO(vtl)).
-//
-// Note: |PlatformChannelPair()|, |PassClientHandleFromParentProcess()| and
-// |PrepareToPassClientHandleToChildProcess()| have platform-specific
-// implementations.

-// Note: On POSIX platforms, to write to the "pipe", use
-// |PlatformChannel{Write,Writev}()| (from platform_channel_utils_posix.h)
-// instead of |write()|, |writev()|, etc. Otherwise, you have to worry about
-// platform differences in suppressing |SIGPIPE|.
