You could just read the manual and use /bin/read, instead of rewriting 
it.

So you get

{
	while () {
		line=`{read}
		echo line: $line
	}
} < filename

Somehow putting the < filename after the inner } makes rc reopen it for 
each loop iteration.  (Am I misinterpreting this?)

A more convoluted way to do to the same thing would be

{ echo 0 > /srv/something.$pid } < filename
while () {
	line=`{read /srv/something.$pid}
	echo line: $line
}
rm /srv/something.$pid

but that's probably better for showing off /srv to your friends than it 
is for actually solving the problem.
