  No, it does it a million times.  Well, it does once you rename the file to
'makefile', as otherwise the recursive sub-make doesn't find it because
'makefile.dat' is not one of the default names it looks for.  Are you *sure*
you really ran the same test as the one you've sent us?

  I've been running it in the background for 45 minutes now and it hasn't
done anything unusual.  Looking at the windows task manager, there are no
memory leaks nor handle leaks; none of the figures are steadily increasing,
they're all varying slightly up and down around their resting values.  It
does hog a lot of cpu resource and occasionally causes applications to pause
for a while, but it doesn't seem to be doing any real harm.

  As to your question, "how do i solve/work around resource temporarily
unavailable", I would have thought it's obvious.  You wait a while and try
again later when it isn't unavailable any more.


    cheers,
