Hello.

Please don't do top-posting to mailing lists.

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.
