Do we, Abi code, open (fopen() ) that file stream.

My changes would not affect coverage figures. Since I don't do Unix
currently´, and even that I do know how to make these changes I currently
won't (so call me stubborn :-) ). At least not until performance figures
have been displayed. Should anyone Unix see the need to fix this, you all
know what to alias by using a ptr or ref. from my earlier post.

Well, I don't have access to any coverage analyzer, but I sure have access
to a performance analyzer that rocks. :-)
OK, I'll do an (somewhat) optimized build and see how this turns out (though
it will not be 100% accurate since I have to turn off some flags to get
somewhat real figures). I can't promise anything, but I hope it will be
within the next day or two. If it appears I forgotten it, please remind me
since I have a s**t-load of other stuff to do also (but I don't want this
one to just be forgotten, so I really like to be remonded in case it seems I
have forgotten it).

I think we all have more stuff that's more pressing atm, but I'd add it
pretty high in the TODO files. Unless (!) someone lurking feel they want to
try something. This is reasonably easy and would put your name in the
CONTRIB file. :-) Anyone want to do this? (pleeease!)
Anyway, I think it should be added to the TODO. Could you add it Sam?

Done, and (according to my own complaint) I'll also post a commit message.

Well, isn't this perhaps a place of "premature optimization"? (OK, I don't
know at all what monster of a machine you run :-) ).

There you go, AW *is* ... (fill in that space yourself, but perhaps "kicking
a**" is a template? :-) ).
