While that almost certainly constitutes "significant fragmentation"
it probably has very little effect on performance.  It _would_
affect performance if that file were being read sequentially, but
ELF binaries don't get loaded that way.  Individual pages are
read in via demand paging, and the next page needed could be from
anywhere in the file.

Bob Nichols         Yes, "NOSPAM" is really part of my email address.
