示例1: find_and_remove
// placeholder used to track class loading internal states
// placeholder existence now for loading superclass/superinterface
// superthreadQ tracks class circularity, while loading superclass/superinterface
// loadInstanceThreadQ tracks load_instance_class calls
// definer() tracks the single thread that owns define token
// defineThreadQ tracks waiters on defining thread's results
// 1st claimant creates placeholder
// find_and_add adds SeenThread entry for appropriate queue
// All claimants remove SeenThread after completing action
// On removal: if definer and all queues empty, remove entry
// Note: you can be in both placeholders and systemDictionary
// see parse_stream for redefine classes
// Therefore - must always check SD first
// Ignores the case where entry is not found
void PlaceholderTable::find_and_remove(int index, unsigned int hash,
symbolHandle name, Handle loader, Thread* thread) {
