 // 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.)
