If you can't reproduce the failure on your own machine, with the same OS, often the cause seems to be heavy multi-tasking on the CI machines, which will slow down timing-sensitive tests to the point of failure.  But even that is hard to prove, since CI is a black box to most of us; and even if you get access to a CI machine to run tests on, they won't fail because it's not multi-tasking so heavily at that time.

A virtual machine with very limited resources can often reproduce such test failures. At least VBox lets you change CPU execution cap while the virtual machine is running.
