This test has a couple of threads running, and passes &error_abort to
the qio_channel_socket_readv() function. So I expect that one thread
is closing the socket connection, and the other thread has not yet
shutdown cleanly, so tries to readv on a dead socket triggering the
error_abort.  IOW,  qio_channel_socket_readv is likely just the symptom
of brokeness somewhere else in the test, not the cause.
