 288 History List
 289
 290   The basic idea here is that we want to keep as much history as we can without paying
 291 a high price in terms of memory space.  Because we keep the history for display purposes,
 292 we can take advantage of the fact that when the period shown in the graphs is long
 293 then each pixel represents a long period.  So as the most recent history we keep one
 294 window full of points at a resolution of 1 second, the next window full at 2 seconds,
 295 the next at 4 seconds and so on, up to the maximum desired.  This way there is always
 296 at least one sample point per pixel for any update delay set by the user, and the
 297 memory required grows with the *log* of the total time period covered.
 298   The history is kept in a doubly-linked list, with the most recent snapshot at the tail.
 299 The number of nodes in the list is fixed, and there are no calls to RemoveHead() and
 300 AddTail() which would add overhead and contribute to memory fragmentation.  Instead,
 301 every second when a new point gets recorded, one of the existing nodes is recycled;
 302 it is disjoined from its present place, put at the tail of the list, and then gets
 303 filled with new data.   [Emilio Sandoz]
 304   This unfortunately does not work with stl classes, as none of them supports moving
 305 a node to another place, so we have to erase and re-add nodes.
 306 */
 307
 308 void CStatistics::RecordHistory()
 309 {       // First we query and compute some values, then we store them in the history list
 310
 311         // A few comments about the use of double and float in computations:
 312         // Even on a hi-res screen our graphs will have 10 bits of resolution at most,
 313         // so the 24 bits resolution of a float on 32 bit Intel processors is more than
 314         // enough for all displayed values.  Rate computations however, and especially
 315         // running average computations, use differences (delta bytes/ delta time), and
 316         // for long uptimes the difference between two timestamps can lose too much
 317         // accuracy because the large mantissa causes less significant bits to be dropped
 318         // (same for the difference between two cumulative byte counts).  [We don't store
 319         // these values as integers because they will be used in floating point calculations,
 320         // and we want to perform the conversion only once).  Therefore timestamps and
 321         // Kbyte counts are stored in the history as doubles, while computed values use
 322         // float (to save space and execution time).
