Yes - the parent catches it as well:

# ps -opid,logname,ppid,uid,command -ax | grep ftp
1623 userfifteenchar 1576 1016 ftpd: snowdrop.l8s.co.uk: usersixteenchars: PWD 
1624 userfifteenchar 1576 1015 ftpd: snowdrop.l8s.co.uk: userfifteenchar: FEAT
# ps -opid,logname,ppid,uid,command -p 1576       
 PID LOGIN           PPID UID COMMAND
1576 userfifteenchar    1   0 /usr/sbin/inetd -l

There is probably a child that alredy calls setsid(), I can't remember
if netbsd lets session leaders call setsid, SVR4 doesn't.
