   This failure reproduces every time when using a fast machine with a single logical processor, only in Windows 2012 R2.

   This test was introduced in v0.10.26 and did not fail like this then. The problem started when v0.10 merged with v0.11, introducing this test there, meaning that v0.11 had the cause of this problem before. Using the test on previous revisions, the first bad commit is 2b6e078 . This does not help much, but is coherent with what @Trott observed in #4062 (comment) . Still investigating.
