Subject: In pty_close(), call del_io_events with the SUDO_EVLOOP_ONCE flag
X-Git-Tag: SUDO_1_8_17^2~45
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=994f86b40fac6773cef9168915b1aad575624629;p=sudo

In pty_close(), call del_io_events with the SUDO_EVLOOP_ONCE flag
so the event loop will exit after a single run through.  Otherwise,
we may hang at exit on non-BSD systems.
