I'm failing to understand how getrusage() works, which is a bit perplexing, because it doesn't seem like it would be terribly complicated. I've attached the code. My aim is to verify that I can use getrusage() to do (admittedly crude) instrumentation of which functions in my program are allocating lots of memory[1]. So I figure I can call getrusage() at various points and look at

Occasionally stopping amd freezes my system. It's a rare occurrence, and I haven't found a reliable way to reproduce it. It's also a real freeze, so there's no way to get into the debugger or grab a core dump. I only can perform the 4 seconds hard shutdown to revive the system. I run amd through sysutils/automounter, which is a scripting solution that generates an amd.map file
