[issue12856] tempfile PRNG reuse between parent and child process

[Antoine Pitrou]

Antoine Pitrou <pitrou at free.fr> added the comment:

Interesting, thank you.
Two nits:
- the test must be skipped where os.fork() isn't available (namely, under Windows)
- I would do os.read(fd, 100) (or some other large value) rather than os.read(fd, 6), so that the test doesn't depend on the exact length of the random sequences produced
