Add numeric option for forkmode param
-------------------------------------
Key: SUREFIRE-465
URL: http://jira.codehaus.org/browse/SUREFIRE-465
Project: Maven Surefire
Issue Type: Improvement
Components: process forking
Reporter: Eric Smalling
Priority: Minor
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.
