Comment (by cohosh):

 > Reproduce the proxy-go deadlocking bug #25688

 It might be useful to spawn several clients in the docker container for
 testing and bug-reproduction purposes. At the moment, I am using the
 torrc-localhost file for the torrc configuration on the client side, but
 we can have only one client bound to each local socks port at a time, and
 tor processes cannot share a datadir.

 What I have done manually so far is copy the client executable and torrc
 file to different directories and added the SocksPort line to each new
 torrc file with a different port number per client instance. I'm thinking
 of expanding the script.sh script to specify a --num-clients option that
 will do this copying SockPort configuration automatically (we don't even
 really need different directories for each client, just different socks
 ports and datadir's).

 While I'm at it, I will probably include a --build option to the script
 that will only compile the code if needed. Since we are mounting the git
 repository from the host directly, this does not need to be done each time
 the container is started.
