这就是“共享内存”吗？ IPC 对象已删除？
可能的重复：
在 Linux 中使用 ipcrm 删除共享内存
我运行的是 Fedora 15 64 位。我有一些共享内存没有被进程清理。当您调用ipcs -m时，您可以看到共享内存：
------ Shared Memory Segments --------
key shmid owner perms bytes nattch status
0x51012a29 294919 trevor 666 194400 2
当我调用ipcrm -m 294919，然后检查共享内存是否被删除时，您会看到：
------ Shared Memory Segments --------
key shmid owner perms bytes nattch status
0x00000000 294919 trevor 666 194400 2 dest
IMO 共享内存仍然存在...因为它在我调用 ipcs -m 时显示。这个共享内存真的被删除了吗？

deleting shared memory with ipcrm in Linux
I am running Fedora 15 64 bit. I have some shared memory that wasn't cleaned up by a process. You can see the shared memory when you call ipcs -m:
------ Shared Memory Segments --------
key shmid owner perms bytes nattch status
0x51012a29 294919 trevor 666 194400 2
When I call ipcrm -m 294919 and then check to see if the shared memory is deleted you see:
------ Shared Memory Segments --------
key shmid owner perms bytes nattch status
0x00000000 294919 trevor 666 194400 2 dest
IMO the shared memory is still there... because it shows up when i call ipcs -m. Is this shared memory actually deleted?

做一点谷歌搜索。这是我发现的；
dest 显然意味着标记为将被销毁。我猜它不会被销毁，除非它被引用或处于暂时状态。

Do a little bit of googling. Here's what I found;
dest apparently means marked to be destroyed. I am guessing it will not be destroyed unless it is being referenced or a transitory state.
