SnapDB Library
Half
Provides a light weight exclusive lock that is approximately 2.5 times faster than Monitor.
WARNING: This lock should be used in a Using block, and duplicate calls to Lock without releasing will cause a deadlock.

Remarks
After writing this class I did some review of the methodology.
Reviewing this article: http://www.adammil.net/blog/v111_Creating_High-Performance_Locks_and_Lock-free_Code_for_NET_.html
Brings up stability issues with the lock. Namely what happens when unhandled exceptions occurs when acquiring and releasing the lock.
I have intentionally left out any kind of protection against this as it severly reduces the speed of this code. Therefore
do not use this locking method where a Thread.Abort() might be used as a control method.
Constructors
Methods
| Equals | Determines whether the specified object is equal to the current object. (Inherited from Object) |
| Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object) |
| GetHashCode | Serves as the default hash function. (Inherited from Object) |
| GetType | Gets the Type of the current instance. (Inherited from Object) |
| Lock | Acquires an exclusive lock on this class. Place call in a using block. Duplicate calls to this within the same thread will cause a deadlock. |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object) |
| ToString | Returns a string that represents the current object. (Inherited from Object) |
