If I set up my RQS like this:

  limit users {*} hosts {@certain_hosts} to my_resource=some_value

then it looks like I am allowed to use no more than 'some_value' on one host. 
That is, one slot seizes all of 'some_value' and I can run only in one slot 
per host, no matter how many more slots are free. But what I would like is 
more or less the opposite: that one slot can not request more than 
'some_value' so that I can run in more than one slot with each taking at most 
'some_value' (in fact what you are saying: the resource limit should be 
multiplied by the requested number of slots which, however, does not appear to 
be the case).
