Running darcs concurrently

[Sven Panne]

While we are at the darcs topic: I get problems most of the time I run 
several "darcs pull" commands for the same server, but different repositories 
on that server via SSH (cryptic messages about not being able to get some 
patches etc.). Somehow darcs seems to share the SSH ControlPath (see 
External.getSSH), reusing a single socket in /tmp/darcs-ssh. Obviously, it 
screws things up sometimes then, so I do not run several pulls from e.g. 
darcs.haskell.org in parallel anymore. Does anybody else have this problem?

Cheers,
   S.
