This is awesome.
Yes!
It was this very problem that initially got me thinking about threads
(and from that, it was just a hop, skip and a jump to Guile) years ago.

I think we need to yield when a thread is waiting for I/O.
Yes, I think that needs to happen pretty much automatically. Perhaps
it would be sufficient to make the Lisp functions that can cause
process filters to be run also yield to other threads.
And, we
probably need a way to associate a process filter with a thread, so
that
whatever input Gnus gets is processed in the right thread.
Yes, and this is an area where Gnus could be changed to take advantage
of it once the facility is a bit more stabilized. The output from one
NNTP server can be processed into a list of newsgroups in one thread,
while another thread converts IMAP output into a list of mailboxes, a
third thread talks to yet another IMAP server, etc.
It might be interesting to look at Apple's Grand Central model, and
see if something like that is practical to use in elisp with dynamic
bindings...
