Different UIDs should not be messing with the same config dir anyway.
The UID in the socket name is there just to allow different users run
different instances of Claws Mail at the same time, not to prevent DoS
Also, I feel we're getting a little bit carried away there with
XDG_RUNTIME_DIR and everything. Supporting XDG would be great, but we
don't, right now.
Maybe we can start caring about XDG_RUNTIME_DIR when we'll have
migrated our config dir to XDG_CONDIR_DIR and imap caches to
In the meantime I couldn't care less if the socket name is rendered
unique using UID, config-dir-name hash, md5sum of the user's full name
appended to the computer domain name or whatever.
Ratinox's patch is good as it is, there's no need to add the UID

That's misguided, we sure as hell don't want two users running two
instances of Claws Mail, writing UIDL files, preferences and IMAP cache
files in the same configuration directory.
Having the unicity on config dirs only is actually better than on UID +
config dir. Of course the hash has to be on the absolute path.
Or am I missing something there?
