I find the resulting documentation page about Python Events a bit hard 
to follow.  The "events.new_thread" event registry refers to the 
gdb.ThreadEvent type, which itself is defined under the "events.cont" 
registry.  There it says that inferior_thread is always not None in 
none-stop, and always None in all-stop.  That is contradictory with the 
text under "events.new_thread".  If it is possible for event types to be 
emitted by different event registries, I think they should be documented 
separately (on the same page, but in two sections).
