PS5, Line 332: probe_pos
Maybe we could rename this guy to next_probe_pos, for better readability.

In theory, this could cause an UB (integer overflow. I wonder if UBSAN build 
would detect it). At that point we have bigger problems to worry about, but not 
too hard to fix with different ordering:

bool is_consecutive_pos = false;
if(current_probe_pos_ != INVALID_ROW_ID) {
  const step = *next_probe_pos - current_probe_pos_;
  is_consecutive_pos = step == 1;
}
