Description Mike Gilbert gentoo-dev

It would be nice if portage would run the pkg_pretend phase in parallel jobs.

For example, when installing KDE/Plasma 5, every ebuild which inherits kde5.eclass runs the kde5_pkg_pretend function. This takes a few minutes to complete for around 60+ packages.

Some notes:

* build log should be combined with the pkg_pretend log (they are currently separate because the build dir is destroyed in between)

* parallel-fetch tasks should be started at the same time as pkg_pretend

The pkg_pretend phases run in a coroutine since bug 710432, so running them in parallel should not be much work.

The UI will look very close to the existing emerge --jobs UI.

We need pkg_pretend scheduling to be aware of package fetch status (for retry) as described in bug 936287 comment #2.
