* Allow to use GTK's main loop instead of the select stuff in
wait.c
* a op_keylist_start should cancel a pending keylisy operation on the
same context
* need to close a lot of handles in w32-io.c

* posix-io.c (_gpgme_io_select): Use a 1 sec timeout and not 200
microseconds.
* wait.c (remove_process): Don't close the fd here.
(do_select): Set the fd to -1 and remove the is_closed flag everywhere.
(_gpgme_wait_on_condition): Remove the assert on the queue and
break out if we could not find the queue. The whole thing should
be reworked.
* posix-io.c (_gpgme_io_set_close_notify): New.
(_gpgme_io_close): Do the notification.
* rungpg.c (close_notify_handler): New.
(_gpgme_gpg_new): Register a callback for the fd.
(_gpgme_gpg_set_colon_line_handler): Ditto.
(build_argv): Ditto
2001-02-13 Werner Koch <wk@gnupg.org>
* rungpg.c (struct reap_s): Replaced pid_t by int.
