Opening a file on a windows share by dragging it from Explorer and 
dropping it into Emacs takes many many seconds.
Doing the same operation on Emacs 22.3.1 is almost instantaneous.
The file is in a large subversion 1.6 checkout, which may or may not be 
relevant

In GNU Emacs 23.0.93.1 (i386-mingw-nt5.1.2600)
  of 2009-05-02 on SOFT-MJASON
Windowing system distributor `Microsoft Corp.', version 5.1.2600

Thanks, there was a / missing from the regexp in 
locate-dominating-stop-dir-regexp, so the search wasn't actually 
terminating at the root of UNC drives, instead a fruitless and time 
consuming search for a machine on the network called ".dir-locals.el" 
would occur.
