TASK DESCRIPTION
  Moved here from: https://bugs.kde.org/show_bug.cgi?id=264219
  
  Original description by Rapheal:
  
  > We already use a QProcess in CliInterface, so there should be no reason for also running it from a separate thread. Besides all the hell associated to running threaded code, it is unnecessary and causes problems with main loops such as the one in CliInterface::runProcess() -- if CliInterface::failOperation() is called (when a wrong password is entered in a header-protected file), KJob::emitResult() will end up being called somewhere in the call stack, and will terminate the auxiliary thread running our QProcess, finishing the event loop before the process is terminated correctly.
