Comment:

 I tried for a while to reproduce this, but wasn't able to.
 However, some of the test output tripped me up to the potential cause.

 So I've pushed a set of changes that I //think// will make this test more
 reliable.
 [[https://github.com/torproject/stem/pull/3|GitHub pull request]] (branch
 head `6ddc67f62689e5b34a1a969a1d022c3c653599b5`)

 I dug into the original implementation of `get_microdescriptors()` and the
 evolution of its test case, just to try to understand if something more
 was going on here. As far as I can reason about this without reproducing
 the failure, these are appropriate changes to make. Please feel free to
 take all or a subset!

Comment:

 Can't assign and switch status in the same step, so here's an intermediate
 edit.

 A [[https://jenkins.torproject.org/job/stem-tor-ci/3443/console|recent
 Jenkins test run (`Build #3443 (May 25, 2018 9:40:56 PM) `)]] indicates
 that our `test_get_microdescriptors` test may be a bit unreliable:
 {{{

 Later test runs have passed, and nothing major has changed in the code.
