Comment(by craigcitro):
Ok, new version of the code is up. This is done differently than last
time; rather than patch our python, I'm simply inserting the code in our
`setup.py`, and calling distutils with the new code '''only''' from Sage.
So, to test this, do the following:
* download and apply trac-4652-testing.patch
* set the env variable `SAGE_PARALLEL_DIST` to anything
* set the env variable `MAKE` to something like `make -j168` (where 168
is the number of simultaneous threads you want)
* `sage -br` or `sage -ba`
If this seems to work for people, then we can try building Sage from
scratch with it. (I'm going to try setting my machine to do that overnight
with `4.0.1.rc2`, I think.) If it works fine, I just want to add a little
bit of documentation and then I'm happy to have this merged. If it works
for a release or so, I'll start working on getting '''something''' like
this upstream. (I have no idea how uphill that battle will be.)
