I tried:
(benchmark-run
1
(call-process "dd" nil (with-current-buffer
(get-buffer-create " *zeroes*")
(set-buffer-multibyte nil)
(current-buffer))
nil "if=/dev/zero" "bs=4096" "count=250000"))
and then jumped to the buffer, and Emacs hung anyway. (That is, I
killed Emacs after a minute, so I don't know whether it would have
recovered after a while...)
