Right. The string representation of the exception is computed in a
fixed-size buffer. You can easily change the size of this buffer
(declaration of "struct stringbuf" in byterun/printexc.c). Ideally,
the buffer would grow as needed...

That's a known open issue. The C code that traps and display the
exception could call back into Caml to perform the flushing (and more
generally all "at_exit" processing), but some care must be taken if
some of this processing raises an exception itself :-)
