Csh & foreach causing fork problems

[Ralph Doncaster]

I'm having problems with a script I made to mail all the students on our
system.   I often get a "fork: no more processes" error.
I assume this is because foreach starts a new process for each argument it is
given.
How can I solve this problem?
Here is the script:

#!/bin/csh
# bm (batch mailer) by Ralph Doncaster, Jan 25/91
# script to mail message to all accounts in /u/student
# usage: bm subject file
if ($#argv) then
	foreach i(`/bin/ls /u/student`)
		mail -s $1 $i < $2
		sleep 1
	end
	echo "Sending message file " $1 "to all accounts in /u/student."
else
	echo "Usage: bm subject file"
endif
