These are just different messages for the same value of errno.

No, it's expected. That script tests the behavior when the process's open
file limit (`ulimit -n') is set to something very small. It's interesting
that AIX (you're running AIX, right?) chooses to return -1/EMFILE even
though the process doesn't have the maximum number of file descriptors open.
