I don't know whose csh you're using, but look at this:

Script started on Mon Nov 20 15:34:11 1989
lakart!dg(~)[61]-> ( sleep 200; cat /etc/passwd >/dev/null) &
[1] 3639
lakart!dg(~)[62]-> ps agtp0
  PID TT STAT  TIME COMMAND
 3623 p0 S     0:01 -h -i (/bin/csh)
 3639 p0 S     0:00 -h -i (/bin/csh)
 3640 p0 S     0:00 sleep 200
 3644 p0 R     0:00 ps ag
lakart!dg(~)[63]-> ^D
script done on Mon Nov 20 15:34:24 1989

Now, by my estimation, the subshell was pid 3639, and as ps shows 3639 is
a /bin/csh.
