for a modified file:

when I try to attach strace or gdb to the svn process, they hang too.
when I attach with visual studio, nothing happens (I don't know how to
get the information you require: stack is not displayed &c).
when I do "break all", I get a message "the process appears to be
deadlocked (or is not running any user-mode code). all threads have been
stopped".
the call stack then is:

        ntdll.dll!7d6264ff()    

when I do "detach all", I get an error "cannot detach".
when I do "terminate all", emacs behaves as is svn terminated normally
and successfully.
please let me know if I could do anything else, but I would appreciate
_detailed_ instructions on any operation with visual studio.
