    Description

      running DJGPP default DOS Extender, cwsdpmi.exe, cause ntvdm use up whole CPU and freeze:

      (subsystems/ntvdm/dos/dos32krnl/dos.c:2843) DOS Internal System Function INT 0x2F, AH = 43h, AL = 0h NOT IMPLEMENTED!
      (subsystems/ntvdm/dos/dos32krnl/dos.c:1751) Setting interrupt 0x2f ...
      (subsystems/ntvdm/dos/dos32krnl/dos.c:2791) DOS Function INT 0x21, AH = 31h, AL = 0h NOT IMPLEMENTED!
      (subsystems/ntvdm/dos/dos32krnl/dos.c:2843) DOS Internal System Function INT 0x2F, AH = 43h, AL = 0h NOT IMPLEMENTED!
      (subsystems/ntvdm/dos/dos32krnl/dos.c:1751) Setting interrupt 0x2f ...
      (subsystems/ntvdm/dos/dos32krnl/dos.c:2791) DOS Function INT 0x21, AH = 31h, AL = 0h NOT IMPLEMENTED!

      if running normal DJGPP program which has a DOS stub that runs cwsdpmi.exe if no DPMI environment available, DJGPP program simply exits.
