Synchronization primitives based on spinning

Structs

Mutex	This type provides MUTual EXclusion based on spinning.
MutexGuard	A guard to which the protected data can be accessed
Once	A synchronization primitive which can be used to run a one-time global initialization. Unlike its std equivalent, this is generalized so that the closure returns a value and it is stored. Once therefore acts something like a future, too.
RwLock	A reader-writer lock
RwLockReadGuard	A guard from which the protected data can be read
RwLockUpgradeableGuard	A guard from which the protected data can be read, and can be upgraded to a writable guard if needed
RwLockWriteGuard	A guard to which the protected data can be written
