// The crash reporter failure collector attempts to report crashes in
// crash_reporter that occur while it's processing a crash.
// In linux, if the program in /proc/sys/kernel/core_pattern crashes after being
// invoked, the kernel logs a special message and does NOT re-invoke the
// program. anomaly_detector picks up that message in logs and invokes
// crash_reporter (which runs this collector and hopefully doesn't crash again).
