Comment (by s7r):

 @starlight do you have any suggestions for a fix? Shipping Tor into
 separate packages as mentioned on the mail list(tor-core; tor-relay and
 tor-client) is not a good option. A warning message is trivial to add but
 a patch is even better.

 Quoting you:
 //Correct support of simultaneous client and relay function requires
 segregation of the client function to a separate thread running on a
 different processor core than the relay function.//

 If we would just add a separate worker to the same daemon (same torrc
 file) to handle the client function, wouldn't that be a fix? Don't know in
 what measure this is possible, but the more we automate it the better.
