The problem on OSX was that closing the same FD in the child process 
would result in the EBADF. The change in the error handling posted 
before made the error more visible. The actual fix for OSX was to make 
sure a single FD was closed only once. See also PR #363 
https://github.com/apple/swift-corelibs-foundation/pull/362, especially 
https://github.com/apple/swift-corelibs-foundation/pull/363/commits/3fd0df28107847b7121f6cb2f823fbad9e2ddcff.
