Hmmm. So this is what is returned:

4.3.3 is GNU Fortran (GCC) 4.3.3 20080912 (prerelease)
trunk is NU Fortran (GCC) 4.4.0 20081206 (experimental) [trunk revision 142525]

4.3.3: 899675 kB (and about 33min)
trunk: 1145308 kB (and about 45min).

this is on the same machine, so times can be compared (module enable
checking?).

However, for the memory usage, top (oh no) showed 2.3-2.5Gb, which is quite
different from what the script returns?
