That is based on misunderstanding (IMHO).  The problems which started 
this thread are OUTSIDE DJGPP.  It is not CWSDPMI that makes the machine 
reboot, it's Windows!  In my experience, many commercial vendors would in 
such cases say it's Windows' fault, go yell on uncle Bill.

When DJGPP runs under a DPMI server, it cannot ``exit from any existing
protected mode''.  Many DPMI environments (Windows is a notable example)
just won't let you do this.  You don't want that your DJGPP programs will
cause a GPF or pop messages like ``This application has compromised the
system integrity and will be terminated'' when run under Windows, do you?
