[stunnel-users] New libwrap code

Hi all,

My apologies if this has been discussed (I've reviewed the
archives since 4.21 was released), and if so please just
point me in the right direction.

I read in some of the messages there's been a revamp
(overhaul, changes, whatever) of the libwrap code in
Stunnel-4.21. I'm not having any issues using the new
version, however, I'm seeing it spawn 5 processes where
in every other version I've used in the past there has
always only been one process spawned. Here's what I see:

root 3408 1 0 17:50 pts/10 00:00:00 /usr/bin/stunnel
root 3409 1 0 17:50 pts/10 00:00:00 /usr/bin/stunnel
root 3410 1 0 17:50 pts/10 00:00:00 /usr/bin/stunnel
root 3411 1 0 17:50 pts/10 00:00:00 /usr/bin/stunnel
root 3412 1 0 17:50 pts/10 00:00:00 /usr/bin/stunnel
stunnel 3413 1 0 17:50 ? 00:00:00 /usr/bin/stunnel

Is this a product of the new libwrap code? I turned debug
messages WAY up and I see over and over startup messages
for all 5 processes. Example of one:

When I connect to swat (Samba config tool) it again goes
through a process of using all 5 of the system processes.
Sorry for being so verbose here. My question is:

Has something changed so that there is more than one
process spawned (and used) when Stunnel is started?

Any help would be appreciated.
