    15 // Mac note: OS X has getdirentries, but it only works if we restrict Chrome to

    16 // 32-bit inodes. There is a getdirentries64 syscall in 10.6, but it's not

    17 // wrapped and the direct syscall interface is unstable. Using an unstable API

    18 // seems worse than falling back to enumerating all file descriptors so we will

    19 // probably never implement this on the Mac.
