OK, here you go:

  # Copyright (C) 2006 T. Schwinger - Boost Software License

  # boost_root must be set here
  echo removing outdated tests:
  bin_dir=$boost_root"/bin/boost" # remove /boost for v2
  for lib_test_dir in `find $boost_root/libs -type d -name test` ; do
    lib_dir=`dirname $lib_test_dir`
    lib=`basename $lib_dir`

    echo - checking library $lib

    jamfile=$lib_test_dir/Jamfile
    jamfile_ts=$jamfile"_timestamp"
    if test -r $jamfile ; then
      if test -r $jamfile_ts ; then
        if test "`find $jamfile -type f -newer $jamfile_ts`" = "$jamfile" ; then

          echo +- Jamfile has changed, removing test target files
          rm -rf $bin_dir/libs/$lib/test

          touch -r $jamfile $jamfile_ts
        fi
      else
        touch -r $jamfile $jamfile_ts
      fi
    fi
  done

Test and integrate at will -- putting 'echo' before the 'rm -rf' sets dry run mode.

Even the integration of this snippet should work incrementally so the second run is the first that can detect changes. 

No overhead is involved (except for the few seconds the script takes to run).

(-;  this one works quite well for motivating people, I figure ;-)
