This was discussed on freebsd-hackers not so long ago. It is possible to
bandwidth limit connections by a simple

while () {

If course, sleep(), or usleep() are not appropriate for squid, but how
hard would it be to implement an algorithm which says "OK, I'm supposed
to read max 3000 chars/sec; I just read 1500 chars; I must not read again on
this connection for at lease 500 ms."??

My guess is that it would need a bandwidth and an "earliest time for next
read" to be stored for each (outbound?) tcp connection.

One could also limit write()s so that delivery is throttled.
