fixes issue 984

We cannot use whether a system library has been loaded as a condition
for whether to swap the state, as we need to make that decision at
gencode creation time.  Rather than going back and re-generating
gencode and handling complexities of changing strategies later, I
downgraded the optimization to just check whether there's a client
library.
