Package for classes that wrap shared memory primitives

Hello, 9 days ago I sent a message to this list with proposal for such package. I asked whether somone will PEAR-ify the code I had written. Today I did this (hope that it is by the PEAR's coding standards). The file is (shm.php) is attached. The code provides class wrappers for shm_var, semaphore, shm_var guarded with semaphore and implementation of a class that is useful for protecting a server from loading too much instances of a script. In fact the script is loaded but a shm_var guarded with semaphore is used to protect the server from running too many instances of this script. This class is useful for backend scripts that directly communicate with some frontend like Java applet(or application). However it may be useful in the traditional web enviroment. A test case is included in the file. Prerequisite is that php must be compiled with --enable-sysvshm and --enable-sysvsem. Please advice a name for this package. I cannot find appropriate category for it thus for now it is Shm. Regards Andrey Hristov
