Could it be that this happens when during ``some stuff'' you do after 
shelling to DOS you press Ctrl-C or Ctrl-BREAK?  If so, it seems that 
RHIDE catches SIGINT right after it returns from the child.  (By default, 
if RHIDE didn't do anything special, signals in DJGPP are passed to 
the parent program as well.)

There are several facilities in DJGPP to prevent signals from being 
passed to the parent program.  Perhaps in the case of shelling to DOS 
RHIDE should use one of these facilities.
