// Class for tracking sandbox violations.  Currently it just logs them to
// stdout and the system console.  In the future it may do more.

// What makes this possible is the fact that Apple' sandboxd calls
// notify_post("com.apple.sandbox.violation.*") whenever it's notified by the
// Sandbox kernel extension of a sandbox violation.  We register to receive
// these notifications.  But the notifications are empty, and are sent for
// every violation in every process.  So we need to do more to get only "our"
// violations, and to find out what kind of violation they were.  See the
// implementation of nsSandboxViolationSink::ViolationHandler().
