If you're doing many lookups prior to connecting to the machines or
otherwise processing the information, you can create a very simple thread
class to perform just the lookup, store the threads in a list, and poll the
threads in the list so you can deal with the ones that finish first before
moving on to the remaining ones.  You'll still have a 25 second wait for the
last ones to finish, but you can get the majority of the work done earlier
than you would with a single-thread program.
