I'm finally find the problem. If domU write to xenstore some
incomplete command by writin binary data to /proc/xen/xenbus
(for example "\2\0\0\0\0\0\0\0\0\0\0\0\21\0\0\0") and exists, watches
stop working and second attemp to read/write some from domU to
xenstore failed with process lock  that tries to write message...

Can this be solved (or solved already in some version of xenbus driver code?).
