 Out of curiosity, I tried to vary the flags provided to msync(2) to no
 effect.  Since the code subsequently does an munmap(), I decided to
 comment out the msync() calls entirely with the same effects but
 with the time spent in break(2) instead.
 
 Note that this is on a not-very-current -current.
 
 Brian.
