You should always use a mutex for global variables when dealing with multiple threads. This is particularly important on multicore systems -- the mutex doesn't just prevent race conditions, it forces two cores to sync their memory (one core could change the memory, and the other core might not know, old memory in cache, until the mutex forces it to sync).
