NSNotification 检测其他程序崩溃
我计划编写一个小守护程序来检测另一个应用程序是否崩溃，一直认为系统会发送 NSWorkspaceDidTerminateApplicationNotification，但事实并非如此。
假设我不想创建 launchd 进程来简单地重新启动崩溃的应用程序，我可以通过其他方式检测崩溃吗？
也许我可以监控系统日志？这似乎过于沉重。
I was planning on writing a small daemon that detected whether another app crashed, thinking all the while that the system would send an NSWorkspaceDidTerminateApplicationNotification, but this is not the case.
Assuming that I do not want to create a launchd process to simply re-launch the crashed application, can I detect the crash any other way?
Perhaps I could monitor the system log? That seems unduly burdensome.

监视
/usr/sbin/spindump进程是否/何时启动怎么样？How about watching for if/when the
/usr/sbin/spindumpprocess starts up?事实证明，最有效的崩溃监视器是读取 FSEventStream 中的崩溃日志。
Turns out what worked best as a crash monitor was reading the FSEventStream for Crash Logs.
