libc: avoid static table and supurious reads in nsec() use two per process memory slots, one for the pid and one for the fd instead of a global table avoiding the case when the table gets full. instead of calling pread() on the cached fd (dangerous as it has side effects when the fd was not closed), we check if the cached fd is still good using fd2path() when called the first time in this process.
