-// Mac note: OS X has getdirentries, but it only works if we restrict Chrome to
-// 32-bit inodes. There is a getdirentries64 syscall in 10.6, but it's not
-// wrapped and the direct syscall interface is unstable. Using an unstable API
-// seems worse than falling back to enumerating all file descriptors so we will
-// probably never implement this on the Mac.
