Okay, after chatting with __ap__ on irc, here's what I think the behavior
should be:
sys.flags.hash_randomization should contain just the value given by the -R
flag. It should only be True if the flag is present, False otherwise.
sys.hash_seed contains the hash seed, set by virtue of the flag or envar. It
should contain the *actual* seed value used. E.g. it might be zero, the
explicitly set integer, or the randomly selected seed value in use during this
Python execution if a random seed was requested.
If you really need the envar value, getenv('PYTHONHASHSEED') is good enough
for that.
