Glib::Threads:Private

[John Emmas <john creativepost co uk>]

I realise it's a deprecated interface but can anyone explain what 
Glib::Threads:Private<SomeObject> does?

Does it guarantee that 'SomeObject' can only be accessed by code running 
in a particular thread?  And if so, does it do that by creating a 
specific thread for the object - or does it use whichever thread was 
running when Glib::Threads:Private got called?  Hope that makes sense....
