On IBM i this test fails asserting the write queue size.
The test expects the queue size to be greater than 0 but
the queue size is 0 on IBM i.
66160d6973/test/test-tcp-write-in-a-row.c (L75)
The test expects the write to get queued because the size of the data
is larger than the send and receive buffers.
66160d6973/test/test-tcp-write-in-a-row.c (L39-L40)
For some reason the request does not seem to get queued on IBM i.
The root cause of the issue will need further investigation.
Part of #4143
Switch from old-style ASSERT macro to new-style ASSERT_EQ,... macros.
Using new-style macros makes it easier to debug test failures
Fixes: https://github.com/libuv/libuv/issues/2974
Pass the loop to MAKE_VALGRIND_HAPPY() so it's explicit on which loop
needs to be cleaned up. Since it asserts on uv_loop_close(), need to
remove a couple of those that were being done before the call.
Cleanup where loop was assigned, so the entire test either uses loop or
uv_default_loop(). Not both.
Also take care of any reqs that may have been left uncleaned.
