+        as soon as overload_count is higher than uwsgi.cheaper_overload (--cheaper-overload options)
+        at most cheaper_step (default to 1) new workers are spawned.
+
+        when at least one worker is free, the overload_count is decremented and the idle_count is incremented.
+        If overload_count reaches 0, the system will count active workers (the ones uncheaped) and busy workers (the ones running a request)
+	if there is exacly 1 free worker we are in "stable state" (1 spare worker available). no worker will be touched.
+	if the number of active workers is higher than uwsgi.cheaper_count and at least uwsgi.cheaper_overload cycles are passed from the last
+        "cheap it" procedure, then cheap a worker.
+
+        Example:
+            10 processes
+            2 cheaper
+            2 cheaper step
+            3 cheaper_overload 
+            1 second master cycle
+    
+            there are 7 workers running (triggered by some kind of spike activity).
+	    Of this, 6 are busy, 1 is free. We are in stable state.
+            After a bit the spike disappear and idle_count start to increase.
+
+	    After 3 seconds (uwsgi.cheaper_overload cycles) the oldest worker will be cheaped. This will happens
+	    every  seconds (uwsgi.cheaper_overload cycles) til the number of workers is == uwsgi.cheaper_count.
+
+	    If during the "cheap them all" procedure, an overload condition come again (another spike) the "cheap them all"
