No, there are also semaphores and read-write locks. RW-locks are

especially useful in cases where there's a single writer but multiple

readers (typically any data distribution).
In general, threading is a wrong way to go if you find sharing and

locking a lot of data between the threads. Threads should be able to

execute fairly independently to properly utilize resources. Naturally

there are typically scatter-gather points which are supposed to be short

compared to overall thread execution time.
