I tried to do that, but I think Sphinx has a memory leak (this has been
suggested before). For whatever reason, after a little while it uses a lot
of memory and slows way down. Actually, the inventory build sped up (from
almost 2 minutes before down to about half a minute on an OS X machine
with 2 cores), but the html build does not.
In more detail, I tried importing sage.all once, and then using a Python
function call to build each document: I basically stuck all of custom-
sphinx-builder.py into builder.py, and replaced the `subprocess.call(...)`
with
{{{
from sphinx.cmdline import main
main(args)
}}}
This way sage.all would be imported just once, not 75 times. But there are
issues. Maybe we should call `main(args)` some other way, so the memory is
guaranteed to be released afterward? Any suggestions?
