    Avoid crash on OS X: guarded fd exception
    
    On OS X, a file descriptor that shows up as being of type "KQUEUE" in
    lsof output is apparently created behind the scenes when starting a
    thread. (Related to BSD kernel event queues: see man kqueue.) When we
    re-exec ourselves on OS X, and then close all file descriptors >= 3,
    closing such a KQUEUE fd causes a crash.
    
    Guard against this by closing only regular files.
    
    (cherry picked from commit 73a508f574995f09559c003cb810e5d2ff2691c2)
