On x86 Gentoo Non-Debug with X 3.x buildbot, test_peg_generator timed out twice after 15 minutes (first time when tests are run in parallel, then when the test is run sequentially).

Maybe the buildbot worker is just slow. On a previous build (749), test_peg_generator timed out after 15 min (parallel run), but then passed in 12 minutes when re-run in verbose mode.

The buildbot worker should get a larger timeout. I suggest to increase the timeout, or the test should be optimized to take less time.

Pablo: Would you mind to increase ware-gentoo-x86 timeout? Ex: 30 min instead of 15 min.
