用于应用程序管理堆外内存区域和避免垃圾收集(GC)导致的延迟的机制就是一个此类的扩展。

内存管理器依赖作为相邻内存slab的堆,因此当堆需要扩展时无法分配更多本机内存;所有堆内存必须预先保留。
The memory manager relies on the heap being a contiguous slab of memory, so it's impossible to allocate more native memory when the heap needs to expand; all heap memory must be reserved up front.
我们知道,一个Windows外壳扩展即是一个进程内的COM服务器,它在Windows资源管理器执行某种动作时装入内存——如显示上下文菜单。
