Natively parallel? From https://docs.julialang.org/en/v1/base/multi-threading/ : "Julia is not yet fully thread-safe. In particular segfaults seem to occur during I/O operations and task switching."

One solution for numerical code at least is to use Numba to JIT-compile (with LLVM, as Julia does) code that can be run without using the GIL, which can be run in parallel on top of Python's threading mechanisms (threading.Thread, concurrent.futures), or with Numba's other options (parallel-for, CUDA kernels, CPU or GPU vectorized Ufuncs/GUfuncs, stencil kernels).
