# TEST	env018
# TEST	Test getters when joining an env.  When a second handle is 
# TEST	opened on an existing env, get_open_flags needs to return 
# TEST	the correct flags to the second handle so it knows what sort
# TEST 	of environment it's just joined.
# TEST
# TEST	For several different flags to env_open, open an env.  Open
# TEST	a second handle on the same env, get_open_flags and verify 
# TEST	the flag is returned.
