When linking our job is done as soon as the file is written, and the liker can just exit.

The situation is a bit more complicated with the current library arrangements since we unfortunately support running in the same process.

This is in the noise when linking clang, but with scyla it goes from 3.894365061 seconds to 3.879345710 seconds (1.0038 times faster). It would be interesting to see numbers on windows too, but I only have a windows VM.
