I don't see how this could be a Cygwin issue. If writing to a file (while it is open) doesn't immediately update the last modified time on Windows, there is no reasonable way for Cygwin to "fix" that. IMHO, this is a very dubious "feature" to depend upon. If you want to know if the file has changed, why not check its length instead?
