I've notice some strange behaviors when using a predefined ThreadID like
"RemoteOffice-ThreadID", on a first request, everything is fine, but
some objects OIDs seems to be persistant event after the socket
deconnexion. I guess when they are cleared ?! So I use a unique one now.

well, I'm not sure how Office is done, but from the tests I've made :
- with XInitialize the server do not send any request
- with an XInputStream the server request some interfaces like
XSeekable, XCloseable, call some methods (seek, readsomeBytes...) but
this is done on an other thread, and then the XComponent OIDs is send on
the main ThreadID.
