The code looks like this:

(setq process (start-process ...))
(process-send process ...)
(process-send-region process ...)
(process-send-eof process)
(accept-process-output process ...)

If we use SYNC_INPUT, I don't see where Emacs would read any keyboard input
between start-process and accept-process-output.  I suppose that pinentry
uses the tty in that time-frame...

Would someone pls. test if it works with the change I suggested --
possibly after recompiling Emacs with CFLAGS=-DSYNC_INPUT ...
