Comment (by simonmar):
I don't see how to avoid this easily: we need to parse the imports of
every source file in order to construct the dependency tree, and we can't
parse the imports without preprocessing the source file first.
Perhaps keeping a cache file containing the imports for each source file
with the last-modified date of the source?
