True to the PEP, this reduces the number of syscalls by roughly 1/3 on Linux.
I used strace -f at2 scan|& grep <scanned path> | wc -l to count the number of syscalls for a directory with 18155 files and 2101 directories (20256 entries total). On master, 58666 syscalls were issued, and with this change the new count is exactly 20256.
