  I'll have to research a bit about the details of memory and disk (it's
already late night here). 

  I recently found a C++ class to measure time spent between lines of code,
but this is fortran. I don't see the profiling tools I know of (gprof,
gconv, mpatrol) as able to measure time line by line. Any tool/suggestion to
do it fortran (which is not my "mother tongue")?
