    Description

      I've noticed that when calling lcb_open against a bucket which does not exist, lcb is trying to connect (which is fine of course), but for some reason it seems to not time out ops that are scheduled in the meantime.

      Consider the code in https://github.com/couchbaselabs/couchbase-rs/blob/master/couchbase/examples/kv.rs#L14, but instead of opening "travel-sample", just choose a name which does not exist. The following logs show what LCB is doing in this case:
