	 * Interned strings that hold class entries can get a corresponding slot in map_ptr for the CE cache.
	 * map_ptr works like a bump allocator: there is a counter which increases to allocate the next slot in the map.
	 *
	 * For class name strings in non-opcache we have:
	 *   - on startup: permanent + interned
	 *   - on request: interned
	 * For class name strings in opcache we have:
	 *   - on startup: permanent + interned
	 *   - on request: either not interned at all, which we can ignore because they won&#039;t get a CE cache entry
	 *                 or they were already permanent + interned
	 *                 or we get a new permanent + interned string in the opcache persistence code
	 *
	 * Notice that the map_ptr layout always has the permanent strings first, and the request strings after.
	 * In non-opcache, a request string may get a slot in map_ptr, and that interned request string
	 * gets destroyed at the end of the request. The corresponding map_ptr slot can thereafter never be used again.
	 * This causes map_ptr to keep reallocating to larger and larger sizes.
	 *
	 * We solve it as follows:
	 * We can check whether we had any interned request strings, which only happens in non-opcache.
	 * If we have any, we reset map_ptr to the last permanent string.
	 * We can&#039;t lose any permanent strings because of map_ptr&#039;s layout.
