I didn't even know there was a splitRef...

It'll have to be something like:

  QVector<QStringRef> pidList = out.splitRef(QRegularExpression(QStringLiteral("\\s+")), QString::SkipEmptyParts);
  // remove duplicates
  std::unique(pidList.begin(), pidList.end());

I'd better do it in a separate commit, given it's really going to change stuff here (that compiles BTW, so I know it works).

Interestingly running `lsof | wc -l` on my system gives 162709; so yeah, we should definitely replace QList with QVector and QString with QStringRef here. :D
