indexing process causes unresponsive system until OOM-killed

[montchr]

As I was running rippkgs-index for the first time, my desktop session froze / became unresponsive. Eventually, the nix eval process was terminated by the OOM killer.

I then saw that my terminal application no longer had any active sessions/frames. Unfortunately, the index output file is nowhere to be found.

I've included some logs below. Let me know if you need more info. However, I feel reluctant to make another attempt to build an index until this issue is fixed or there is some other way to provide an index (#30).
