Thanks.  I cannot spot anything significant: the traces look almost
identical, and the code of the suspect function (emulated `stat') is
virtually the same, up until the point where the value of
w32-get-true-file-attributes is checked (the value of which you said
made no difference).

Previously you said that with Emacs 22.x, the number of file ops is
889, but I don't see so many ops in the trace you posted to the above
URL.  What am I missing?

I also don't see the 15-sec delay in the trace: both the trace from
Emacs 22.x and from 21.x show about 2-3 seconds between the first
syscall and the last.

Please help me understand the data.
