That "even" changes the meaning completely of the sentence. If you leave it
out, the sentence makes sense for the generic case.
It does not apply to QProcess though: QProcess is always waiting for the child
process to finish.

That question does not make sense. QProcess is always waiting for the signal,
which is delivered asynchronously.
Note: you're posting to the mailing list discussion development _of_ Qt. I am
assuming that you have run into a situation that you believe to be due to a Qt
bug. When you send the testcase, I will not be trying to fix it for you -- that
is not the intention of this mailing list.
If you are uncertain whether your code is correct, then we're talking about
development *with* Qt. That's the interest at qt-project.org mailing list. Please
post there if that's the case.
