内存free的疑问
...that free memory remains allocated to the process. However, if it’s not being
used, the Linux memory manager will be able to page it out from physical memory to swap space,

Remember that once you’ve called free on a block of memory, it no longer belongs
to the process. It’s not being managed by the malloc library.
出自beginning linux programming的Data Management小节,不大理解allocated to the process
却又no longer belongs to the process,还有就是所谓的linux memory manager和malloc library
的关系,请指教
