I've ran the CI on my fork and found a couple of clang-tidy complaints which have now been fixed. I've also committed b240861 which fixes the macOS CI. |

@DaanDeMeyer Do you have any thoughts on this? I see someone ended up debugging the same issue in #105. |

@DaanDeMeyer Is there anything missing in this PR for it to be reviewed ? |

I've ran into issues using reproc inside containers due to the limit on the number of open file descriptors being more than 1024^2. I see the same issue has been seen by other people:
This PR removes the hard coded limit, though obviously that can make starting a subprocess extremely slow. To avoid this performance issue I've modified the code to only close open file descriptors when possible. I've tested this with macOS and Linux and it should be robust to other unix systems.
Do you have any thoughts on this approach?
