[packagekit] Weird timeout issue in PK zypp backend

[Zhu, Peter J]

Any help here. Libzypp author can't find hints of such delay within libzypp. I can also verify this with pkcon refresh which would result immediate update in /var/cache/zypp but search still got old result until a time delay. 

Seems to be issue of how PK zypp backend talks to packagekitd. PK zypp backend uses pk_backend_thread to finish each called backend function, anything special should be keep in mind here?
