+# The following settings allow you to control the number of workers that can run
+# on a given node, to prevent the node from becoming overloaded. 'max_workers' 
+# is a simple cap on the maximum number of workers a node is allowed to run
+# concurrently. 'max_load' is the maximum (one-minute) load average, above which
+# a node will refuse to take new work. 'min_free_memory' is the minimum amount
+# of free RAM (in megabytes) a node is allowed to have, below which no new 
+# workers are run. These settings may be used in any combination.
