With NumPy, I am still there in the waitinglist, number 92. So I guess
it will take a while.

I see, yes.

Thanks for the write up. Yes, I have exactly the same experience
with SymPy's pull requests. So I have personally spent
a lot of time trying to streamline the process and making sure
that we can trust it and so on. My bet is that Travis CI
will be *the* tool of choice for most projects at least on linux,
to test the pull requests.
