Re: Async package.el

[raman]

Also, attempting to make package async shows up a problem that is lying
in wait as Emacs gets multithreading capabilities -- most elisp packages
are written assuming a sync/blocking world -- especially with respect to
user-feedback. So even as package downloads and installs things
asynchronously, the underlying elisp modules that download, unpack and
compile output messages continuously in the echo area -- wonder how
distracting that is to someone who can see. I can say that it well-nigh
makes things impossible with Emacspeak at present --  I need to find a
way of telling #'message   not to talk when called from an async
task  -- or more generally, if called from anything except the main UI
thread. Any ideas?
