I don't unterstand you. I didn't change the test case. It still above and is 
still marked with todo.

This change simply ensures that the next test is not distorted. If wine does 
not pass the test

"WriteFile on an overlapped handle without ovl structure should fail"

but instead sends the bytes we should wait long enough before starting the 
next test so that there are no remaining bytes in the tx buffer. Otherwise the 
next test will not test sending 17 bytes but much more.
