    Using an array of Async<unit> for the workers and

    a shared token between threads.

    Compile : 

        fsc --tailcalls+ -O --platform:x64 ThreadRingNew.fs -o ThreadRingNew.exe

    Execute :

        mono ThreadRingNew.exe 50000000


let NumberOfThreads = 503

let mutable (workers : Async<unit>[]) = null
let mutable token = -1

let createWorker i = 
    let next = (i + 1) % NumberOfThreads
    async { if token = 0 then 
                printfn "%d" (i + 1)
                exit 0 
                token <- token - 1
                return! workers.[next] }

let main args = 
    token   <- int args.[0]
    workers <- Array.init NumberOfThreads createWorker
