Hi Philippe,

this failing test seems to be flaky. Is it possible to fix this? Maybe increase the timeout?

TestFoundation/TestNSURLSession.swift:254: error: TestURLSession.test_downloadTaskWithURLAndHandler : Asynchronous wait failed - Exceeded timeout of 12.0 seconds, with unfulfilled expectations: download task with handler

Thanks,
Erik

This failure has been coming up very intermittently for a while when running TestFoundation locally.

Though we have a new commit in URLSession (015ded4d70a7cf4b2741d7206fc60a3d1ceffe03), I don't think that change can trigger this failure. Nevertheless, I'll try to reproduce it locally and investigate.
