# In AIX, if getrlimit(2) is called multiple times with RLIMIT_DATA,
# the first call and the subsequent calls return slightly different
# values of rlim_cur, even if the process does nothing between
# the calls. This behavior causes some of the tests in this spec
# to fail, so call Process.getrlimit(:DATA) once and discard the result.
# Subsequent calls to Process.getrlimit(:DATA) should return
# a consistent value of rlim_cur.
