If some workers are disabled, the others will still be scheduled correctly.

for each worker in workers
     worker lbstatus += worker lbfactor
     total factor    += worker lbfactor
     if worker lbstatus > candidate lbstatus
-       candidate = worker
+        candidate = worker
 
-candidate lbstatus -= total factor

If a balancer is configured as follows:

- 

-    worker     a    b    c    d
-    lbfactor  25   25   25   25
-    lbstatus   0    0    0    0
-
+ + + + + + + + + + + + + + + +
workerabcd
lbfactor25252525
lbstatus0000

And b gets disabled, the following schedule is produced:

- 

-    lbstatus -50    0   25   25
-    lbstatus -25    0  -25   50
-    lbstatus   0    0    0    0
-    (repeat)
-
-

That is it schedules: a c d a c d a c d ...

lbstatus-250-2550

That is it schedules: a c d + a c d a c + d ...

The following asymmetric configuration works as one would expect:

- 

-    worker     a    b
-    lbfactor  70   30
-
-    lbstatus -30   30
-    lbstatus  40  -40
-    lbstatus  10  -10
-    lbstatus -20   20
-    lbstatus -50   50
-    lbstatus  20  -20
-    lbstatus -10   10
-    lbstatus -40   40
-    lbstatus  30  -30
-    lbasatus   0    0

That is after 10 schedules, the schedule repeats and 7 a are selected with 3 b interspersed.
