yep! Sorry to bother you again with this number-of-connection issue. Tor
on my network status machine is a non exit relay with a rather
restrictive bandwidth policy of "BandwidthRate 50 KB" and
"BandwidthBurst 100 KB". Even this tiny middleman relay holds 10000+ tcp
connections. Probably this number of connections will kill most routers
used in residential environment.

Even the paper describing a method for priorization of interactive
circuits
http://www.cacr.math.uwaterloo.ca/techreports/2010/cacr2010-06.pdf gives
me no clue why the number of tcp connections is growing.
