`loading` and `cmdlineargs` fail with max copying

[udesou]

Both tests fail with a somewhat similar output:

• loading:

  Expression: success(addenv(`$(Base.julia_cmd()) --project=$project_path --startup-file=no -e 'import Pkg; Pkg.develop("Foo51989"); Pkg.precompile(); exit(0)'`, "JULIA_DEPOT_PATH" => depot))

• cmdlineargs

Simplified the cmdlineargs failure a bit.

The command:

/home/diogo/Code/MMTk/julia/usr/bin/julia -C native -J/home/diogo/Code/MMTk/julia/usr/lib/julia/sys.so -g1 --bug-report=rr-local -e 'exit()'

Fails with this stacktrace on my machine:

Ok, it fails with different stacktraces sometimes.

I think this could be related to ccalls not being properly handled in Curl:

┌ Error: socket_callback: unexpected error
│   err = TypeError: in typeassert, expected Downloads.Curl.Multi, got a value of type Base.RefValue{Compiler.RTEffects}
└ @ Downloads.Curl ~/Code/MMTk/julia/usr/share/julia/stdlib/v1.13/Downloads/src/Curl/Multi.jl:213

This is caused by the same issue here #257.

We're now running these tests, with max copying, in CI: #273.
