# The setting  LACSLOWDOWN=0.52  helps  "xorgbase" to  build even on a
# flaky old system,  but increases  build times  from about 3 hours to
# over 6 hours  just to get past building "xserver".  The  addition of
# LACSMPTRIES=4 may,  or may not,  make it  possible to  increase LAC-
# SLOWDOWN, and thereby build speeds.
