Linux /proc/PID/stack profiler

proc-profiler

This is a simple Linux wall-time kernel-stack profiler that reads /proc/PID/stack.

On Linux you should use perf for CPU profiling, or eBPF for both CPU and off-CPU profiling. Or just about anything else, including application traces. If you actually need my proc-profiler, you must have a really busted up system you need to debug. As I did, when I wrote this thing.
