  Modified files:
    sys/i386/linux       linux_machdep.c 
  Log:
  Linux does not filesystem-sync file-backed writable mmap pages on
  a regular basis.  Adjust our linux emulation to conform.  This will
  cause more dirty pages to be left for the pagedaemon to deal with,
  but our new low-memory handling code can deal with it.   The linux
  way appears to be a trend, and we may very well make MAP_NOSYNC the
  default for FreeBSD as well (once we have reasonable sequential
  write-behind heuristics for random faults).
  (will be MFC'd prior to 4.3 freeze)
