Hi Alex,

I don't think there is, unfortunately. I've tried my best to split up
the swig files to minimize the memory footprint and compile time, but
it's just too large a project.

Johnathan and I have been kicking around some ideas that might be able
to help in the far future. But for right now, I haven't found anything
that can reduce the build issues further. I tried to go in an find as
many instances of %include that can be replaced by %import, but there
really weren't that many.

One thing to do with the memory issue is to set make to only build
with 1 thread (no parallelism). It'll take longer over all, but it
will keep the memory footprint pretty small. The main problem is when
swigging multiple blocks_swigX files at the same time.
