[Bug 452477] [NEW] some files get blocked or not found when a DOS program is runned in 2 different simultaneous sessions of DOSEMU

[dmayer]

Public bug reported:

i am trying to run a program on DOS running DOSEMU on UBUNTU and
everything works fine the first instance. When i try to open the same
program in another DOSEMU window, i get errors as if some of the files
of the program are not accessible or can not be found. this same program
runs multiple times with no problems on a real DOS on windows
enviroment.

 It seems that DOSEMU enviroment is bloççcking or doing something weird
with the file set so the second time i execute my app in the second
DOSEMU window i get this error:

cannot find grales.LBR
cannot find gestion.LBR
Load failure (179) on file: \bit\gestion\menu
press any key to continue ... (if i press any key here it exits to the command prompt)

if i exit my application on the first window but i remain inside dosemu
and in the second dosemu window i try to execute the app, ewverything
runs fine now, so its obvious that some files are being blocked or
something like that, but i dont think is my app doing it because in
windows it does not happend when i run multiple times the same app.

i can open multiple DOSEMU PROMPTS but i can run the app in only one of
them

DOSEMU 1.4.0.0 ius being used
