The main scenario I'm trying to improve on is
readdir-followed-by-stats. Through GVFS, this occurs when showing a
File Browser of a share, or a File Open dialog, etc. Because the stats
are done sequentially, directories with many files are painfully slow,
even on networks with decent bandwidth, like a Wifi connection.
Issuing the stats asynchronously would alleviate this problem and
would better use the bandwidth available on the link.

I have a proof of concept in smbclient4 that does this. It's a toy
problem, a 'dir' which also shows streams information for each file
entry. But async qpathinfo2 against an XP server does seem to work,
and it does speed things up.

It seems I neglected to check the latest version of the Samba 3 client
API - I was under the impression that it did not have an async request
interface. I see cli_qpathinfo2_send in source3/libsmb/clirap.h. Is
this part of a supported, stable interface?
