fix: random crash atexit with multithread julia

[dpinol]

Invoke Base._atexit instead of jl_atexit_hook to avoid invoking finalizers, which might crash with multithread julia

[cjdoris]

Hmm I'd rather not rely on any more Julia internals (Base._atexit).

Perhaps jl_atexit_hook is being called from multiple threads and is not thread safe? Perhaps a lock and ensuring it only gets called once will.fox your issue.

Do you have a MWE for your issue?

• I don't see any lock at jl_atexit_hook: https://github.com/JuliaLang/julia/blob/master/src/init.c#L256
• Lock is at _atexit: https://github.com/JuliaLang/julia/blob/master/base/initdefs.jl#L520

Do you have a MWE for your issue?

Will work on it
