making emerge faster

[Patrick von Reth]

hm true, but we call Python sub instances multiple times and I have no idea
how to cache it for the parent processes.
Caching in a file would make it more complicated, because everyone still has
the possibility to switch back to mingw.org,
and also would not be that much faster.

Greetings
