Earlier, we said that the need for synchronization arises even in the simple case of assigning or incrementing a field. Although locking can always satisfy this need, a contended lock means that a thread must block, suffering the overhead of a context switch and the latency of being ...
All it would take is for the thread to block briefly on a simple lock or synchronization resource, and any pending interruption would kick in. If the method isn’t designed to be interrupted (with appropriate cleanup code in finally blocks), objects could be left in an unusable state or ...
Union,Intersect,Except, andZip), you must applyAsParallel()to both input sequences (otherwise, an exception is thrown). You don’t, however, need to keep applyingAsParallelto a query as it progresses, because PLINQ’s query operators output anotherParallelQuerysequence. In fact, callingAsParal...

Thread-compatible: Such types provide safe concurrent access to const methods but require synchronization for non-const (or mixed const/non-const access). Chrome doesn't expose reader-writer locks; as such, the only use case for this is objects (typically globals) which are initialized once in...
mres.Wait(); // now Wait() on worker and clean up worker.Wait(); mres.Dispose(); } } Remarks For an example of how to use a Spin Lock, see How to: Use SpinLock for Low-Level Synchronization. Spin locks can be used for leaf-level locks where the object allocation implied by us...

Chapter 9. Threading and Synchronization Performance From its first days, some of Java’s appeal has been because it is multithreaded. Even in the days before multicore and multi-CPU systems were … - Selection from Java Performance: The Definitive Guid
We also introduced locking and thread safety, and demonstrated the simplest signaling construct, ManualResetEvent.This chapter picks up where Chapter 14 left off on the topic of threading. In the first three sections, we flesh out synchronization, locking, and thread safety in greater detail. ...
