No IPC, no pain

Hi, Shea. PR isn't appropriate, thus the issue :-)

What do you think about this?

We can do similar thing for fetchgit.

Two questions:

1. What does this gain from being a nix-exec builtin instead of just being defined e.g. in defnix?
2. How is this not IPC? Is it just that we use a shell instead of C++? fetchgit already does that...

[ip1981]

1. It doesn't matter right now
2. No pipes => we can rely on vfork, no fork bomb. Both parent and child know how to find the result fetchgit uses pipes.

Aaah, I see. Yeah good call, I'd love to fix fetchgit that way (been bit by ENOMEM on fork a few times there...)

@ip1981 Any chance you want to implement this? 😁

[ip1981]

The short answer is no. I've been moving in some other way: git submodules and git-crypt.
