Really? I don't know, I haven't actually used it in a while. ISTR it
reporting to some log file, though.

No software is ever finished ;-). It may not be mature, though.

File a bug report, and even a patch! :-)
You're right that a deamon shouldn't have stdin/stdout/stderr open,
and the child process ought not to inherit any file descriptors.
Fortunately the child, in this case, is probably just a small shell
script to restart a daemon, and that daemon will be better behaved and
not leave the descriptors open.

You're welcome.

After you install Microsoft Windows XP, you have the option to create
user accounts. If you create user accounts, by default, they will have
an account type of administrator with no password.
