For tmp.test, I swapped the order of the sleep and the echo in the
fake automake (and changed the sleep to 4) to better emulate the
real automake, failure and success stories follows:

kill failure:

For tmp2.test, my MSYS install does not have sync, so that's a nono...


tmp3.test "always" works, but takes different branches depending
on if kill worked or not.

kill failure:

So, nothing unexpected given my previous message...
