I merged #305 since it seems obviously positive. I am less convinced about arbitrarily retrying: child processes are not guaranteed to be idempotent. If we want to implement a retry around "unzip" specifically on mac, I think that would be reasonable. It should not be implemented for all processes though. |

Close microsoft/vcpkg#21905 bullet point 1.
Code 127 normally means
command not found, but that does not really makes sense here. Sometimes (not often)unzipreturns 127 and sometimes not, when you retry it the return code is 0. I have no idea what the problem could be, but this implements a workaround by retrying the command once on mac when the return code is 127.
