/** \class FastMutexLock
* \brief Critical section locking class.
*
* FastMutexLock allows the locking of variables which are accessed
* through different threads. This header file also defines
* SimpleFastMutexLock which is not a subclass of Object.
* The API is identical to that of MutexLock, and the behavior is
* identical as well, except on Windows 9x/NT platforms. The only difference
* on these platforms is that MutexLock is more flexible, in that
* it works across processes as well as across threads, but also costs
* more, in that it evokes a 600-cycle x86 ring transition. The
* FastMutexLock provides a higher-performance equivalent (on
* Windows) but won't work across processes. Since it is unclear how,
* in igtl, an object at the igtl level can be shared across processes
* in the first place, one should use FastMutexLock unless one has
* a very good reason to use MutexLock. If higher-performance equivalents
* for non-Windows platforms (Irix, SunOS, etc) are discovered, they
* should replace the implementations in this class
*
* \ingroup OSSystemObjects
