This will free/delete all memory owned by the * ICU libraries, and return them to their original load state. All open ICU * items (collators, resource bundles, converters, etc.) must be closed before * calling this function, otherwise ICU may not free its allocated memory * (e.g. close your converters and resource bundles before calling this * function). Generally, this function should be called once just before * an application exits. For applications that dynamically load and unload * the ICU libraries (relatively uncommon), u_cleanup() should be called * just before the library unload. *

* u_cleanup() is not thread safe. All other threads should stop using ICU * before calling this function. *

* Any open ICU items will be left in an undefined state by u_cleanup(), * and any subsequent attempt to use such an item will give unpredictable * results. *

* After calling u_cleanup(), an application may continue to use ICU by * creating an ICU C++ object or opening new items (converters, collators, * etc.) and using them. An application must use ICU from one single * thread before allowing other threads or processes from using ICU. This * is so that the ICU libraries can reinitialize in a thread safe manner. *

* The use of u_cleanup() just before an application terminates is optional, * but it should be called only once for performance reasons. The primary * benefit is to eliminate reports of memory or resource leaks originating * in ICU code from the results generated by heap analysis tools. *

* Use this function with great care! *
