I wasn't talking about that, however.  The C library itself (printf
being the particular case) need not be reentrant: it might use static
data structures etc.  This has nothing to do with MS-DOS specifically,
it's just as true for UNIX and other environments with implementations
of the C language. 

I have been unable to recreate the problem with the program crashing
after about 25 interruptions. Maybe the problem lies elsewhere after all?
