---------------------------------+------------------------------------------
 We added a simple string comparison to keep me`^W`users from shooting
 themselves in their feet by specifying two hidden services with the same
 HiddenServiceDir in the same torrc, but someday we should also put a lock
 file in every HiddenServiceDir to prevent users from shooting themselves
 in their feet in more elaborate ways (e.g. using symlinks, or shared
 network filesystems, or multiple Tor instances).

 The lock file will need to be named something other than `lock` (perhaps
 `hslock`), so that this won't break currently valid (but imprudent)
 configurations that use Tor's DataDirectory as the HiddenServiceDir for a
 hidden service.
