Hi!

Suppose I have a QByteArray with data that should be piped to stdin of a 
process. I need to use blocking mode (everything else is complete 
overkill; we are talking about KMail's "execute" filter action here).

Question: How do I preload the data before calling .start()?
Answer: You can't.

OK, so I tried to use a QObject that would feed the data to the KProcess 
on - umm, yeah on what?
There's no started() signal to which I could connect and writeStdin() 
returns true when the process doesn't run. Hen and egg.

Ergo: Can't use blocking mode and stdin communication.
1. This isn't documented.
2. I need it to fix #38456

Can someone who knows this class have a look?

TIA,
Marc
