28.0.50; USABLE_SIGOI undef code paths do not work correctly |

To reproduce the problem on Debian (at least), edit src/config.h to
this:
/* Define to 1 if SIGIO is usable. */
/* #define USABLE_SIGIO 0 */
Then recompile Emacs and say
(let ((value 'SECONDARY)
(x-selection-timeout 2000))
;;; from org-get-x-clipboard in lisp/org-compat.el
(gui-get-selection value 'UTF8_STRING)
(gui-get-selection value 'COMPOUND_TEXT)
(gui-get-selection value 'STRING)
(gui-get-selection value 'TEXT))
This will hang for two seconds instead of returning immediately if
USABLE_SIGIO is defined.
Now, we have SIGIO on almost all supported platforms. The only ones
that have it disabled might be these ones:
hpux* | nacl | solaris | unixware )
emacs_broken_SIGIO=yes
Which is probably why this hasn't been reported more. (See bug#29170.)
So this isn't exactly a high impact problem, but it should be fixed
anyway.

There's still one more issue related to this bug, which I mentioned earlier: If
x_selection_timeout is zero, x_get_foreign_selection will call
wait_reading_process output with an infinite timeout rather than a zero timeout,
which I'm sure is not what was intended. The attached patch fixes that.
Bu that's clearly what was intended. The doc string of
x-selection-timeout says:
A value of 0 means wait as long as necessary.
Oh, I somehow missed that, sorry. In that case I'm closing the bug.
