Nevermind, I've got it.
When you try to execute something, scan_dir scans all the files on your 
path and on your current directory searching for it.
Even more, it scans multiple times searching for different name 
combinations (exe/com/bat and with different capitalization), and that's 
what causing
huge bandwidth consumption and stalls when you're on a big directory. 
Luckily for me, as I said in another mail I'm mounting the remote novell
partition with ncpmount that makes all acceses to the mounted device 
case-insensitive, so I just made scan_dir return true always, and now I 
think it determines
if a file it's there or not by stating it in find_file. I have 
encountered no problems with this yet.


Another thing, I don't know if this is the proper place to ask for it, 
but I've found that dosemu doesn't work right with dtach.
When you reattach you simply get a black screen and all the text, 
windows, pictures, etc are gone. I can't use screen because for some
reason some programs just hang when they're executed in dosemu inside a 
screen, but they work flawlessly in dtach. It would be
great if you could do something about this. To get around it I added 
this at the end of sigwinch:

SLsmg_touch_lines(0,vga.text_height);
SLsmg_refresh();

It does work now, but I know nothing of slang and the docs say you 
should not use SLsmg_touch_lines, so it has to be a better way.
It would be great if in the next version dosemu and dtach could get along.
