> PermGen memory becomes very full for large sets of junits.  So much so that unless I turn on <forkmode>pertest</forkmode> I have to up my MaxPermGen to over 300m  (we have 2600+ tests)
> Since that slows the tests to a crawl, and since using that much perm space causes problems with virtual memory paging I'd like to see if an option to fork on every n-th test could be added.
> ie: <forkmode>100</forkmode> would create a new fork for every 100 tests.
> I'll dl the source and see if i can submit a patch here too.
