How does the instantiation of a Pool affect the number of Workers spawned in Pthreads?

When instantiating a Pool in Pthreads, the number of Workers spawned is determined by the parameter passed to the Pool constructor. The number of Workers should ideally be equal to the number of available CPU cores to maximize efficiency. To achieve this, you can use the `suggested` method of the Pool class to automatically set the number of Workers based on the number of CPU cores.

$pool = new Pool();
$pool->resize(Threaded::suggested());
