Test failures with 0.9.31

[Andreas Enge]

Hello,

when upgrading from 0.9.30 to 0.9.31 in the GNU Guix distribution,
where all packages are built in a sparsely populated chroot, about
half the tests in testcurl fail with messages similar to
   Failed to bind to port 11080: Address already in use

I attach src/testcurl/test-suite.log. With the exact same setting,
0.9.30 passes all its tests. Our curl version is curl-7.28.1.
