randomizing execution of tests

Greetings hobbit gurus [0],
While I am still trying to search my way to an answer via the archives
of this list and google, I'm hoping someone could point me in the
right direction.
I've got a bb-hosts file with 8 server process instances getting
tested. Each instance gets tested with 3 HTTP requests (2 GET, 1
POST). All 8 server processes live on the same physical OS instance.
This results in 24 HTTP requests getting sent from hobbit within
1/100th of a second. This causes the load on the host to spike, and
generates contention w/in each server to satisfy the requests. This
same setup is repeated for hundreds of hosts and hundreds of processes.
Is there a way to tell hobbit to take all of the entries in bb-hosts
and test them in a random order w/in the 1 minute testing interval?
This would end up staggering the arrival of each HTTP test somewhat
and lessen contention within each HTTP server and on each host.
Thanks,
-dave
