If cheap traps are enabled [debug-options interface], @var{cont} is a
debug object, otherwise it is a restartable continuation.
@var{cont} is a ``debug object'', which means that it can be passed to
@code{make-stack} to discover the stack at the point of the trap. The
apply frame handler's code can capture a restartable continuation if it
wants to by using @code{call-with-current-continuation} in the usual way.
