Can something be done inside the script to make memory more prepared
for heavy computation? I tried putting:

                # Allocate a large buffer just to free it
                a=""
                a="${(r:2000000:: :)a}"
                a=""

before:
                list=( "${(@M)list:#(#i)*$~search_pattern*}" )

But it doesn't make difference
