// This class implements an out-of-process crash server. It uses breakpad's

// 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.
