I would be shocked if this actually worked correctly;  there is a huge
amount of global state inside disksim; multiple instances will corrupt
each other.  If you really need to do this, you can probably fork off
processes and do the synchronization with some kind of ipc.

I've been working on this in my (limited) spare time and I wish it was
done 9 months ago but there are only so many hours in the day :(
