Log:
  ftw(): Do not check the maxfds argument against OPEN_MAX.
  
  Apart from the fact that nothing should have OPEN_MAX as a limit (as opposed
  to RLIMIT_NOFILE from getrlimit() or _SC_OPEN_MAX from sysconf()), POSIX
  does not require us to check this. POSIX does have a requirement on the
  application that maxfds not exceed {OPEN_MAX}, but does not require the
  implementation to check it ("may fail").
