+How the scheduler chooses which limit to apply, based on the MAXIMA
+and LIMIT arrays:
+
+First, the scheduler is only started for an architecture if the number of
+currently scheduled packages is lower than MAXIMA*2. Then if the number of
+scheduled packages is higher than MAXIMA, only new versions are scheduled...
+
+
+Then, for each category (totally _untested_ packages, _new_ versions,
+_ftbfs_ packages and _old_ versions) it depends on how many packages are
+already scheduled in that category, in a 3 steps process.
+
+
+Let's go by an example:
'unstable': {1: (250, 40), 2: (350, 20), '*': 5},
+is translated to:
+
if total < 250:
40
elif total < 350:
20
else:
5
+
* 1st step, if there are less than 250 packages in the queue, schedule 40
* 2nd step, if there are less than 350 packages in the queue, schedule 20
* 3rd step, schedule 5
+
So, the 3rd step happens only when there are more than 350 packages queued up.
