There are some tests in noPassthroughWithMongod/logpath.js which have been disabled on account of SERVER-5117. However, that problem hasn't been present for some time.

These tests should be re-enabled.

They will need to be updated for changes that have happened to the test suite in the interim, eg. MongoRunner opts of { fork: true } will translate to cmdline args of "--fork true", and so { fork: "" } needs to be used instead. Also stopping the process via MongoRunner.stopMongod() doesn't seem to work as expected (though manually connecting and shutting down should work).
