Yes - mine is much simpler :-). I was just doing
the minimal thing that works for Vista.

Doing cacheprime isn't the same as the readahead()
system call on Linux. posix_fadvise is close enough
that I could squeeze it in....

This code gives a marked speed increase for Vista
clients when using explorer against Linux servers.
