crazy proj : No 4 - multi threading

Baiscs:

1. Thread local 

new ThreadLocal<String>(()=>"hehe")

LocalDataStoreSlot  slot ;   Thread.setData(slot,123)

2. Thread with parameters

class MyThread<T>

T data

3. background thread

IsBackground=false

4. control thread

start sleep join abort 

5. ThreadPool

ThreadPool.QueueUserWorkItem(_ => Console.WriteLine(Thread.GetData(slot) == null));

ThreadPool.QueueUserWorkItem(new WaitCallback(ThreadProc));

 

 knowledge:

1. In .NET 4.5 the maximum is 1,000 threads by default on 32-bit processes, and 32,767 threads in 64-bit mode, al­though you can change that—the ThreadPool class has a SetMaxThreadsmethod that lets you configure different limits for your process.

2. By default, each thread gets 1 MB of the process’s address space reserved for its stack, so by the time you have 1,000 threads, you’ll be using 1 GB of address space for stacks alone.

3. I/O and worker threads. I/O invoke methods you provided as callbacks

(modify threadpool size should consider this difference )
