Set the number of script verification threads (\fB\-10\fR to 15, 0 = auto, <0 =
leave that many cores free, default: 0)
```

`\fB` makes the `-10` bold, as if it were a parameter rather than a value.

(Additionally, the `-10` comes from the system of whoever ran the gen-manpages script, and should probably be generated deterministically here...)

     Either install a handler to notify us when genesis activates, or set fHaveGenesis directly.
     No locking, as this happens before any background thread is started.
