tcp batch test is fragile.

This can depend completely on the underlying TCP stack deciding
to segment -- for example if we get context away for a bit, the
stack in kernel can decide to go ahead and close the segment.

There isn't anything useful that this test is testing for, and it
breaks randomly in CI.
