The issue is not the email front-end per se but the email servers (IMAP,
POP, whatever).  A couple of years ago, I ended up having to use an
email server that would take many seconds, often minutes, to access,
even just to query to find out if there was any new email.

The easiest solution, for me, was to get into the habit of starting two
emacs instances.  The first for all my work (org, writing, coding, etc.)
and a second just for email.  The first starts the emacs server so
emacsclient always goes to the non-email instance.  I've been doing this
for two years now and it has become second nature for me.

Obviously, the real fix is to have proper multi-threading in Emacs and,
as in nuclear fusion, this will be with us *soon* ;-)
