It's not strictly necessary, but with higher thread counts you'll still 
hit parallel class installation limits, resulting in slower execution.

If you have more than 4 cores you can find out what number of threads 
works best for you by running:

ant -Dtest262-test-sys-prop.test.js.threads=<#ofthreads> test262parallel

Let me know if something higher than 4 works better.
