Is there a related ticket?

IMO, the CID can be buried down here in the commit message somewhere.
Practically speaking, and I've said it before, the CIDs are a bit
meaningless since they are outside our control and sit behind an
authentication mechanism.

Is it better to ignore the return value, or should there be debug
checking of errno values? I think the only valid return of -1 would be
with errno==EEXIST.
