My initial thoughts for a design were as follows:

- The main test loop starts with doing an openDumpTool(); just prior to that we
would 
    - if total number of outstanding tests was greater than threshold then wait
for an one to finish
    - then fork another test (essentially just forking the perl program)
    - when test is done don't update the $tests{result} hash but rather exit
with an error code
       and have the parent use that error code to update $tests{result}.

Pros:
- relatively simple

Cons:
- extra (perl) process per test

Other ideas:
- perhaps use real threads (rather than processes) to avoid overhead;  not sure
how the SIGPIPE handler would work then.
