We have a similar problem - the upgrade means our slugs have to be recompiled, and heroku's slug compiler times out after 15 minutes. That sounds like a long time, but the development version of gevent can take a good 5-10 minutes to build.

We got an email back from heroku suggesting we push with half the dependencies first, then the other half. Not an ideal solution, as it would take our production app offline.
