It occured to me that I'm using the term "cache coherency" incorrectly
here.  What I really mean to say is that Windows is in charge of all
file operations and so can and does maintain a consistent cache of file
data and attributes because the only path to the file is through the OS.
Cygwin can't because a cygwin process can't (easily) know what other
processes are doing to a file.
