	 * Step-by-step testing
	 *
	 * Every line in this test is structured according to the scheme
	 * '<ops> U(t,c,s,q) <doc>' where the symbols are defined as follows:
	 *
	 * ops  Operations that affect the schedule but not the head of the
	 *      scheduler (which is a buffer to remember the last scheduling
	 *      choice). These operations are:
	 *
	 *      C(s)  construct the context with ID 's' and insert it
	 *      D(s)  remove the context with ID 's' and destruct it
	 *      A(s)  set the context with ID 's' active
	 *      I(s)  set the context with ID 's' inactive
	 *      O(s)  do 'A(s)' and check that this will outdate the head
	 *      N(s)  do 'A(s)' and check that this won't outdate the head
	 *      Y     annotate that the current head wants to yield
	 *
	 * U(c,t,s,q) 
	 *           First update the head and time of the scheduler according to
	 *           the new schedule and the fact that the head consumed a 
	 *           quantum of 'c'. Then, check the consumed time 't' for the
	 *           actual round and if the new head is the context with ID 's'
	 *           that has a quota of 'q'.
	 *
	 * doc  Documents the expected schedule for the point after the head
	 *      update in the corresponding line. First it lists all claims
	 *      via their ID followed by a ' (active) or a ° (inactive) and the
	 *      corresponding quota. So 5°120 is the inactive context 5 that
	 *      has a quota of 120 left for the current round. They are sorted
	 *      decurrent by their priorities and the priority bands are
	 *      separated by dashes. After the lowest priority band there is
	 *      an additional dash followed by the current state of the round-
	 *      robin scheduling that has no quota or priority. Only active
	 *      contexts are listed here and only the head is listed together
	 *      with its remaining quota. So 4'50 1 7 means that the active
	 *      context 4 is the round-robin head with quota 50 remaining and
	 *      that he is followed by the active contexts 1 and 7 both with a
	 *      fresh time-slice.
	 *
	 * The order of operations is the same as in the operative kernel so each
	 * line can be seen as one "kernel pass". If any check in a line fails,
	 * the test prematurely stops and prints out where and why it has stopped.
