Yea but keep in mind anytime you get a bug your session goes away so you can end up eating hours from a day precompiling. Not worth it with heavy pkgs imo. Wish they had incremental compilation like rust because most compiled Lang's are noticeably faster than Julia precompilation ime.

This only happens for Segmentation fault type crashes which kill the entire Julia process, which shouldn't be common at all. Can you describe when you experience these issues?

It's super easy to get ooms and seg. Faults in Julia. For a while there this past year you couldn't even Ctrl c to stop the Julia process. It's rough for real work imo. Fine for research.

I don't remember C-c being broken in the past year. Could it have just been a specific program you were running with a tight loop that didn't have any yield points? If so, that's not really unique to Julia.

I'd also be interested in your workload that was generating lots of seg faults (oom makes some sense if working with large data since Julia's runtime does add an unfortunate amount of memory overhead.

Julia devs seem to work on improving precompilation times every version. That said if a project or workflow revolves around some packages, a way to skip this step is to create a sysimage, essentially a saved Julia session, that includes those packages. PackageCompiler significantly simplifies the process.
