Have you actually observed that this is problem in the specific case
with processExecAsyncTimed?

I am asking because if you have observed it at windows, then what I
thought was a Linux-only issue is also a Windows issue. After all, the
putStrLn only happens in case of an error (negative unicode).

Just to be clear, I am not arguing against the patch, I just want to
know if the processExecAsyncTimed problem also occurs on windows.
