-// This class implements an out-of-process crash server. It uses breakpad's
-// CrashGenerationServer and CrashReportSender to generate and then send the
-// crash dumps. Internally, it uses OS specific pipe to allow applications to
-// register for crash dumps and later on when a registered application crashes
-// it will signal an event that causes this code to wake up and perform a
-// crash dump on the signaling process. The dump is then stored on disk and
-// possibly sent to the crash2 servers.
