It is definitely suspicious. Generally Subclipse does not directly
touch the .svn folders at all. It only makes calls to the JavaHL API
which is just a bridge to the normal SVN API provided in the SVN
DLL's. Cygwin seems to be a relevant wrinkle, but I do not see why
TortoiseSVN would not have problems. I am not aware of any special
handling for Cygwin that it includes.
