Message:

Run tests in separate network namespaces

Creating a network namespace for each test avoids port conflicts so
Apache instances can run in parallel, and also isolates the tests from
the host system.

Test namespaces are automatically used if the "unshare" command is
available, and can be disabled by passing "--disable-test-namespaces"
to ./configure.

test
