To use the legacy BSD selector, you must have a second VCS engine, or else the ABI simply maps the request for another engine onto VCS0. However, we only checked a single VCS1 location and overlooking the possibility of a sparse VCS set being mapped to the dense ABI. v2: num_vcs_engines() turns out to be reusable and futureproof it so we never have to worry about this silly bit of ABI again!
