Document problems and pitfalls with fine-grained hashmap impl

With this refactoring, the Rust code deals with one giant array of
requests, and doesn't know that it's sliced up per backend
process. The C code is now responsible for slicing it up.

This also adds code to complete old IOs at backends start that were
started and left behind by a previous session. That was a little more
straightforward to do with the refactoring, which is why I tackled it
now.

-    // There are a few ways we could work around this:

-    // 1. Change the current directory to the Postgres data directory and use a relative

-    //    applies to the whole process. We could change the current directory early in

-    //    it would be more robust if the data directory is moved around or unlinked for
-    //    some reason, and you would be less likely to accidentally litter other parts of
-    //    the filesystem with e.g. temporary files. However, that's a pretty invasive
-    //    change.
-    //
-    // 2. On Linux, you could open() the data directory, and refer to the the socket
-    //    inside it as "/proc/self/fd/<fd>/neon-communicator.socket". But that's
-    //    Linux-only.
-    //
-    // 3. Create a symbolic link to the socket with a shorter path, and use that.
-    //
-    // We use the symbolic link approach here. Hopefully the paths we use in production
