Adjust block_size to avoid false sharing of cachelines among threads. Currently set to twice the cache line size on Intel and ARM processors.

CancelWait cancels effects of the previous Prewait call.

WARN: It's not thread safe to call it concurrently with `local()`.

Prewait prepares for waiting. After calling Prewait, the thread must re-check the wait predicate and then call either CancelWait or CommitWait.

* Malloc-like interface to the pointer-mapper. * Given a size, creates a byte-typed buffer and returns a * fake pointer to keep track of it. * \par
