New description:

 This unit test relies on removing permissions from a directory to result
 in an error from the platform to tell it that the code under test is
 operating as expected.  This comes with a multi-paragraph comment to
 explain the weirdness.

 Also, since permissions don't work like this on Windows, there's a branch
 in the test for the runtime platform.

 Then, even not on Windows, permissions don't work like this if the process
 has extra privileges, so the test fails sometimes.

 Instead of all this, let's just change the interface of WebishServer so it
 is easy to test.
