Not so.  In fact, I can prove it.  This article got posted, right???
I had my emacs stopped (^Z) and was using rn.  Saw this, and decided
to post.  So, Pnews called up 'ol emacsclient, which printed "Waiting
for Emacs...".  Then I ^Z-ed out of Pnews, and fg-ed my emacs.
Whereupon, server read in the header and I wrote this.  Shortly, I
shall type C-x #, save the buffer, and ^Z emacs and fg Pnews.  And
then, lo and behold, emacsclient will print "Done."...and if I list
the article, it's still there.

No need for subshells, windows, or any other garbage.

Guess why???  Emacs client can connect to a socket even when the owner
is a sleep.  It can even write...remember UNIX?  PSEUDO-synchronized
I/O.  Anyway, once emacsclient has connected and written its little
message into the kernel's buffer, it makes no difference if it runs or
not.  When I resume emacs, it reads that buffer and *POW* there we
are.

Geez.  I wish 'ol RMS would fix the manual on this one.
