goodbye ping loopback if

[paolopas]

Let's look at this beautiful piece of code one last time

t.write("sleep.bat", """\
::@timeout /T %1 /NOBREAK >nul
@ping 127.0.0.1 -n 2 -w 1000 >nul
@ping 127.0.0.1 -n %1 -w 1000 >nul
@exit /B 0
""")

because I removed it from every test it was still in !
It used to be really complicated to get a sleep on Windows, and this has been the solution until now.

The problem is not only depending on network latency, which can change for reasons other than technological ones, but above all running such different tests between the various platforms.

The solution is to use Python everywhere.
