Something's amiss here: the new test fails on MS-Windows because it
signals an error inside eshell-wait-for-subprocess:

  Test esh-proc-test/sigpipe-exits-process backtrace:
    signal(eshell-pipe-broken #<process sh.exe>)
    eshell-output-object-to-target("killed\n" #<process sh.exe>)
    eshell-output-object("killed\n" nil [nil (nil . 0) (nil . 0)])
    #f(compiled-function () #<bytecode 0x1c2b272f8d5f2c5e>)()
    apply(#f(compiled-function () #<bytecode 0x1c2b272f8d5f2c5e>) nil)
    timer-event-handler([t 25107 54636 874750 nil #f(compiled-function (
    sleep-for(0.1)
    sit-for(0.1)
    (while (if all eshell-process-list (eshell-interactive-process-p)) (
    (let ((start (current-time))) (while (if all eshell-process-list (es
    eshell-wait-for-subprocess(t)

Sounds like the shell is already dead/killed when
eshell-wait-for-subprocess tries to send it a string?
