Hi,
We're running into travis-ci time limits when building OSX wheels:
https://travis-ci.org/MacPython/scipy-wheels/builds/ 204105101
The main reason for this is that, for OSX, we are building twice,
first for i386, then for x86_64, and then combining these builds into
a 'fat' binary to be compatible with either architecture. The builds
take a long time, hence the timeout.
I believe that the i386 architecture on OSX is pretty much unused now.
For example, it looks like south of 0.5% of CPUs running OSX cannot do
64-bit:

I propose that we drop the i386 part of the scipy build, but continue
to distribute apparently dual-arch wheels (architecture 'intel') so
that the wheel installs into the Python.org and System Python builds
[1]. This has the added advantage of making the wheel build process a
lot simpler.
Thoughts?
