No, I don't want to change the current definition of reset().
And "not able to do the job" is something different than
"unimplemented".
Why cannot we do a real reset here? Re-exec'in the running binary or
performing a longjmp() to the start might be ideas how to implement
this.
Best regards,
Wolfgang Denk
