I kind of got carried away adding desktop notifications with progress bars to this tool.
The code now uses fstatat, readlinkat and openat to replace worrysome handling of large on-stack buffers with handling of worrysome amounts of fds. Also I removed some unnecessary repeated looping over /proc and an unnecessary intermediate result array. Also, the code is now identifying files by inode number instead of comparing strings. This is simpler and will still work almost always.
If really necessary, I can split this into a proper commit series, however I won't do that before Tuesday.
