    dsynth - Stabilization
    
    * Rejigger the dynamic load management calculations and fix bugs in
      how the restrictions based on pkgdep memory use are calculated.
    
      The pkgdep memory mechanism now supports both slow-start and
      slow-approach.  The slow-approach mechanism begins when pkgdep
      memory use goes about 1/2 the target (typically 1/4 physical memory).
    
      In slow-approach mode, the number of workers is increased at a
      rate of 1 every 30 seconds instead of 1 every 5 seconds in order
      to give workers time to install the packages and fill in the estimated
      memory use.  The idea is that this then allows paging to ramp up
      more slowly instead of getting 'shocked' by a dozen slots all
      issuing install-pkgs at the same time.
    
    * Add -m gb  (in gigabytes), to override the default pkgdep memory
      target.
    
    * For now stop mounting /usr/src in the workers.
    
    * NCurses disablement now works as expected.
    
    * Calculate 1 gigabyte as 1GiB.
    
    * Fix a bug in bulk accounting that could sometimes cause the bulk
      scans to block indefinitely.
