+Subject: [PATCH] make maxCopies unbounded for 'system' and 'misc' suites
+
+Quoting original author of this patch:
+
+Simply un-limits the 'misc' and 'system' suites.
+
+Half-related thoughts about testing quality:
+
+I'm curious why there's a shell1, shell8, and shell16 set of tests. Aren't the
+latter two equivalent to './Run -c 8 shell1' and './Run -c 16 shell1'? I think
+shell8 and shell16 are pointless if this is the case.
+
+At the very least, I think shell8 should be out of the default run (the $index
+set), because it will essentially give a misleading number if you have more
+than a single core in the system. Isn't the purpose of the serial run to
+essentially measure how well the system performs on single-threaded activities?
+Or perhaps to measure how well a single core performs? Having 'shell8' in the
+$index set artificially inflates the score for serialized runs and artificially
+damages the score during maxed-out parallelized runs. If you are actually
+interested in seeing how well 'shell8' does on exactly one core, shouldn't you
+do the equivalent of 'taskset 1' on it, forcing the child processes to stay on
+that single core?
+
+End of quote.
