41 Code locking can severely limit both performance and scalability, so it
47 One of the advantages of locking is that, in happy contrast with the
58 locking functions must carefully prevent both the CPU and the compiler
59 from moving code in either direction across the locking function.
86 Data locking
89 With code locking, we use single-threaded code execution to guarantee
104 As the number of buckets increases, data locking scales naturally.
