i think this is all due to the fact virus scanners like MCAFEE like to see whats going on

The native Win32 Subversion already does this and solves the
virus-scanner/file indexers/tag-along-helper-apps issues in all known
cases. The cygwin version doesn't. So don't use the cygwin version
or convince the cygwin maintainers to include the workaround code.
The root of the problem is Windows file-system semantics with regards
to locking/deleting/moving already open files in combination with
tag-along 'helper' applications that open every file that is created
or changed in order to do something 'helpful' with it. Most Unix
file-systems don't have the problem because they support
moving/deleting files that are open by other applications and they
also have fewer (any?) tag-along type 'helper' applications.
