fork/exec is almost certainly going to be negligable compared to the overall compile time anyway. It's not like GHC is fast enough for it to matter.
Don't count on it. On our Windows desktop machines, fork/exec costs approximately one third of a second, instead of the expected small number of milliseconds or less. The reasons are unknown, but we suspect a misconfigured anti-virus scanner (and for various company policy reasons we are prohibited from doing the investigation that could confirm or deny this hypothesis).
