/// UT_ThreadedAlgorithm takes care of all the thread administration that a
/// threaded algorithm requires.  
///
/// NOTE: UT_ParallelUtil is the modern preferred method of multithreading
///       and should usually be used for new code.
/// 
/// Its features are:
/// 1) it executes work in the main thread as well
/// 2) it assumes that the work can be divided into N parts and sends off 
///    exactly N calls to threadfunc() (jobs). (N depends on the # of 
///    installed processors and the maxthreads parm). 
///
/// Your callback function is called with several
/// useful parameters:
///
///   void * data    - the userdata pointer you provide to run()
///   int  jobindex  - there are N jobs, this is which job you're running
///                    (0 to N-1).
///   int  maxindex  - the total number of jobs farmed (N)
///   UT_Lock &lock  - a lock that you can use to lock other jobs out while
///                    you work on something non-threadsafe. Accepts NULL.
///
/// If your machine is a single proc, this will work exactly as a call to
/// threadfunc().
///
/// In addition to the traditional threadfunc() callback, you can pass
/// in a UT_Functor1 which takes a UT_JobInfo parameter to specify the
/// job to be performed (see below).  In this case, you may be better off
/// with the THREADED_METHOD macros detailed later.
