Notas Sobre Multithreading em Julia

Sobre o uso de `Threads.@threads`

O uso de Threads.@threads deve ser evitado.

Esta macro utiliza um scheduler estático que não funciona muito bem quando temos uma chamada à macro Threads.@threads a partir de uma função que já está rodando em modo multithread.

Só é seguro utilizar esta macro em código top-level quando há garantia de que não há outras tasks executando em modo multithread e para funções que não disparam código em modo multithread.
