    But PATH_MAX is limited and the number of file descriptors is perhaps
    not.

    (On Solaris, PATH_MAX is 1024 so you require at most 512 file
    descriptors to keep the stack of directories: 512 is less than the
    default hard limit of 65536 file descriptors per process [S9, S8
    and before used 1024, still >> 512)
