NSNotification to detect other program's crashes

Question

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.

Answer 1

How about watching for if/when the /usr/sbin/spindump process starts up?

Answer 2

Turns out what worked best as a crash monitor was reading the FSEventStream for Crash Logs.
