To help us pinpoint the problem, could you please try to run the
attached "fake" test scripts multiple times, and post the outputs?
Please forgive me the for the ugliness of such scripts, but I'm just
taking wild guesses here.
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.

So, nothing unexpected given my previous message...
Cheers,
