the "exec" issue is not the point, that was problematic for me. The problem is
the still open stdout/stderr file handle. See my mail from the 10th of January

I did the following:
1) running stunnel 4.20 (no separate libwrap):
The stunnel processes are properly disconnected from stdout/stderr.
See the output of "ps" - especially the "tty" column.
2) running stunnel 4.21 (with libwrap):
The stunnel processes (except for one) are still connected to stdout/stderr.
This can cause programs to hang (e.g. the cryptonas python code, that I referred
to, was waiting forever for the daemon process to finish/disconnect - with 4.20
3) running stunnel 4.21 (disabled libwrap):
The stunnel processes are disconnected from stdout/stderr. It behaves just like
4.20 - no hang or other problems.
If you notice above behaviour (2) for 4.21 (or later) with libwrap enabled, then
I guess, this is a problem, or?
At least, I expected stunnel to disconnect completely from the terminal when
entering daemon mode. If my expectations are flawed here, then we all can safely
ignore this non-issue :)
thanks for your time!
