Yes, but in the resulting project plan TaskJuggler calculates the task
is finished in only one day! And that shouldn't be possible... even if
Harry does not have to work on it, there's no way this task is finished
after one day, only.

But then why isn't it ignored if Harry is not on vacation? (try deleting
the vacation in the "Harry" resource).
It doesn't seem plausible a project can be finished earlier because
of somebody going on vacation...

Hmmm... but the task does not take 10 days of effort from Harry, in fact,
after setting up something it doesn't take any time at all from anybody,
but a computer has to collect some data for at least 10 working days... and
this cannot be done in a day.
How can I describe that appropriately?
