ServiceEvents are defined in the spec as being delivered on the calling
thread (i.e., synchronously). I agree, this sucks and shouldn't be that
way, but the spec says so.

Hi
I just found a deadlock in our code that was the result of the lack of
asynchronicity. When a service is registered in felix, the trackers are
notified in the same thread. Is
it the intended behavior ?
Looks to me that could lead to a very deep stack of invocation, no ? Of
course I can fix this by doing my service regsitration in a separate thread,
but I wanted
to check first with you for input.
Thanks
