Calling getdents()/readdir64() repeatedly while closing descriptors provides unexpected behaviour. Reading directory while it modified is not safe by default. For example: http://en.it-usenet.org/thread/18514/15719/. 

So, we should re-open directory if we received full array of structures. I don't know if just lseek(dirfd, 0) sufficies.

Please reopen bug, as Linux behaviour of stable reading /proc/<pid>/fd may be broken in future without any error at python side (!) (typically, second call returns empty list if dir was modified)
