The test has a long comment in it that says what it's testing: that when running a compilation command with a bunch of subprocesses, the number of polls should roughly match the number of reads. I can't see how that would break on someone else's configuration, but maybe you could modify the test to have it print the problematic value, or try running the individual steps manually and looking at the output.
