I wonder why the cleaning up of those mmaps is synchronous

  I would imagine it is just because it would require more complexity in the kernel. One would need to create a queue of tasks to be performed during cleanup and have the path through the exit system call know to push work onto that queue. It sounds like there is an opportunity for someone to submit a diff to the Linux kernel for improving exit userspace latency.

    I’m guessing a linker like this is also a VERY extreme case when it comes to mmap’ing a huge number of files. For most software, it’s just not that big of an issue.

      But given how universally the linker is required, it might be worth looking into optimizing.
