博客介绍了TThreadList默认忽略添加重复项，大列表下此操作计算成本高，为提升性能可将Duplicates属性设为dupAccept。还提及LockList函数锁定其他线程后返回列表对象，UnlockList过程调用Windows函数，使用LockList后用它让其他线程访问列表。

By default, TThreadList ignores attempts to add duplicate entries to the list. If the list is large, this default is computationally expensive. For better performance, you may want to change the Duplicates property to dupAccept where possible.

function LockList: TList;
Description
LockList returns the TList object that contains the list, after locking out all other threads.

procedure UnlockList;
Description
UnlockList calls the Windows LeaveCriticalSection function. Use UnlockList after LockList to allow other threads access to the list.
