实现UP、DOWN原语
产生3个进程：
两个进程模拟需要进入临界区的用户进程。
当需要进入临界区时，显示：“进程x请求进入临界区…”，同时向管理进程提出申请；
申请返回，表示进入了临界区。在临界区中等待一段随机时间，并显示：“进程x正在临界区…”；
当时间结束，显示：“进程x退出临界区…”,同时向管理进程提出退出申请；
当申请返回，显示：“进程x已退出临界区。”
一个进程作为原语的管理进程，接受其他进程的临界区进入请求：
如果允许进入，则根据DOWN 原语的操作步骤设置相应变量，然后返回；
如果不允许进入，则进入循环等待，直到允许为止；
退出时模拟UP 操作。
进程间通信可以采用信号、消息传递、管道或网络通信方式。
-achieve UP, DOWN original language have three processes : process simulation of two critical needs for access to the users in the process. When the need to access critical areas, revealed : "The process of x request to enter the critical areas ...", and also to the management process applications; applied to return, entered a critical area. In the critical area to wait for a certain period of time random, and that : "the process of x is the critical area ..."; When the time ended, showed : "x withdraw from the process of critical areas ...", and also to withdraw from the process management applications; When applied to ret

Read more about this feature here.
Most, if not all, Portable Network Graphics features as CRC checking are now fully performed.
Error on broken images are now better handled using new exception classes.
The images may be saved using interlaced mode also.
Transparency information won t be discarted after the image is loaded any more.
Most of the images are decoded much faster now.
The images will be better encoded using fresh new algorithms.
IMPORTANT! Now transparency information is used to display images.
