Does this caching really gain us that much? The disadvantage of doing this
is that we have to maintain our own scripts for doing it, since upstream
does not support it.

Perhaps a better way would be to work with upstream to allow the following
interface:

phase 1: build a directory full of tarballs (just symlink the result of
fetchurl without unpacking)
phase 2: let yarn assemble the dependency tree (thus it will deal with
cyclic dependencies for us)

This would only need a feature from upstream to use cached tarballs.
