Steve,

I missed your initial posting.  I see it is on emx, which provides my feed, so
I wonder how I don't have it.  In any case, I've tried your example on 2.2.1
with update 1721 applied and don't see the problem, i.e., I created your
example as described, ran it as both root and guest and all 10 times (2 id's,
5 invocations) produced "foo" as desired.  I don't know offhand if csh was
changed in any of the updates to 2.2.1 (my guess is that you got 1722 when 
you got 2.2.1, but I don't know, of course). sum -r on my csh gives

16773   197 /bin/csh

If you have a different binary, we can try to explore it from that point of
view, otherwise, I assume this is symptomatic of other problems.  I use a few
csh scripts daily, some invoked by absolute path, e.g., /u/bin/errmail:

#!/bin/csh
set month = `date +%m`
set day = `date +%d`
set year = `date +%y`

(errpt -s ${month}${day}0000${year} \
	|& grep -v Diskette \
	|& grep -v tty \
	|& grep -v SNA \
	|& grep -v Tokenring_DLC;\
(echo 'Device             Mounted on            total     free  used     ifree  used';\
	df| grep /dev/hd))\
|& mail -s `uname -n` root

invoked at 2359 by cron, and, of course, which.csh lifted from 4.3/RT, which is
just invoked as which, and have not observed any such problems.
