When I evaluate the following form in "emacs -Q":
(progn
(setq p1 (make-network-process :name "p1" :host "www.fsf.org" :service 80))
(setq p2 (make-network-process :name "p2" :host "www.fsf.org" :service 80))
(setq p3 (make-network-process :name "p3" :host "www.fsf.org" :service 80))
(delete-process p2)
(process-send-string p3 "there"))
I get:
Debugger entered--Lisp error: (file-error "writing to process" "bad file
descriptor" #<process p3<1>>)
process-send-string(#<process p3<1>> "hi")
This is because p2 and p3 are both created with infd=outfd=0, thus
closing the channel for p2 also closes that of p3.

I've undef'ed HAVE_LIBRESOLV and HAVE_RES_INIT in s/darwin.h, as you
