are client messages.  However, this could be either 1. timing errors,
or 2. unusual EINTR or other signal noise.

I also wonder if it's cpu based... I'm Intel and you appear
to be PPC.

Also, if you do these tests back to back, you may also sometimes
see something like:

apr_socket_bind()->48/Address already in use
problem with data read (byte 12495 of trl 3):
read `0' (0x30) from client; expected `@'
apr_socket_recv()->54/Connection reset by peer (expected APR_EOF)

meaning that the previous server didn't go away fast enough
for the "next" server to startup (if you do a lot of these
tests back to back)... These hand tests seem quite sensitive
to timing.
