testing more than one configuration on a single build machine

Hi,

I have recently signed up to run smoke testing of PostgreSQL.
As I understand each animal has a set of configuration that is represented as
icons on the status page.

I wonder how would be it possible to run several configurations on the
same machine? I mean with or without debug, with or without
thread-safety etc.
