Could you pleas explain how this should work with I/O redirection?

We did also discuss the problem if handling signals....
A shell builtin (regardless of what shell you use) needs special
treatement of signals and libfind implements a method that should be
compatible to what ksh93 uses in case that is an adaptation layer.
I am in hope that Roland helps with testing this.
