Do you know why we don't either always see these or always don't see
them? I'm a bit worried there may be a deeper issue lurking here. Are
those events part of the event mask being set?

For reference, I've been looking at the server abstraction in bitbake
and am close to rewriting a large part of bb.server.* and bb.main with
a view to simplifying the code structure and making things easier to
understand.

I've noticed I see some new events with my change, equally I think its
an event mask issue with my new code...

I pushed my changes onto http://git.yoctoproject.org/cgit.cgi/poky-cont
rib/commit/?h=rpurdie/wip-
rss2&id=7d970e7b9f5499f5fcdb0e73246f106844ecf09b
however I am well aware things don't work properly yet and its full of
debug. When finished I should be able to delete server/__init__.py and
server/xmlrpc.py.

Cheers,

Richard
