Context

        Odin: dev-2022-11:f1c24f43
        OS:   macOS Unknown (build: 22A380, kernel: 22.1.0)

Steps to Reproduce

package main

import "core:fmt"
import "core:thread"
import "core:time"

empty_task :: proc(t: thread.Task) {
    for {
        fmt.println("user index should be 1:", t.user_index)
        time.sleep(1 * time.Second)
    }
}

main :: proc() {
    pool: thread.Pool
    thread.pool_init(pool=&pool, thread_count=3, allocator=context.allocator)
    thread.pool_add_task(
        pool=&pool,
        procedure=empty_task,
        data=nil,
        user_index=1,
        allocator=context.allocator,
    )
    thread.pool_start(&pool)
    defer thread.pool_destroy(&pool)

    for {}
}

Current Behavior
