I put debug prints in pinentry-tty, and it is opening the correct tty.
However, running the command to set the terminal into the right mode
will fail.  If I comment that out, something interesting happens:

tty/pinentry-tty.c
356       c =3D fgetc (ttyfi);
357       switch (c)

This call to `fgetc`, while it points to a FILE handle opened to the
correct tty, will read NOTHING.  My session is on /dev/pty0, but a
subprocess that opens that terminal for reading neither fail, nor read
anything.

Any ideas?
