1600 is probably reasonable--is 25%
of the relay population.

The 'lsof' number appears doubled.  Probably
the kernel in use is showing each socket
once for each 'tor' process thread
--two threads is the usual number.

You can obtain more detail by requesting
a connection list on a control channel
with 

   nc 127.0.0.1 9151
   getinfo orconn-status

Authentication may be required by the
control channel.  I use AUTHENTICATE
with a password but I think a token
mechanism is the default (don't know
how that works).  Gruesome details
here

https://gitweb.torproject.org/torspec.git/tree/control-spec.txt

Using <<EOF one can create small
scripts for making control channel
requests.

Output lines beginning with $ are
relays.  You may find user-client
connections (IP only) because some
old botnet is running a pre-guard
version of tor or has disabled
guards.  For a middle relay
only the peer relay count matters.
