[Cuis-dev] Question re: recent updates (4342)

[Juan Vuletich]

Wow. I think there was a random process scheduling bug. It worked OK if 
installing updates from another starting point (I don't even remember 
which), but not if starting from #4322.

I just pushed a new version of update #4342. The fix was to add a Delay 
after spawning the new Morphic process, to give it time to be setup 
before interrupting it. It seems to work now. Please try it.

Thanks, Phil!
