Thanks for looking into it, I don't think the delay was too long at all :)
Am sorry for not making the test output clearer / constructing the case as 
a proper unit test, was the last thing on a too long day it seems..

Yep it seems to work perfectly in the build you used: after clearing event 
handlers by iterating thru the GetInvocationList(), adding event handlers 
again from ironpython works (like it did in 2.0 alpha5 but not in 1.1), 
and also adding c#-written event handlers in ironpython always works (it 
always borked for me in 2.0 alpha5, works in 1.1).

Will test alpha6 myself also soonish.
