Subject: Put internal events at highest priority
X-Git-Tag: release-2.0.8-rc~16^2
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=90651b327a9819e890e8ababe1e46f3fa989850c;p=libevent

Put internal events at highest priority

(If we allow user events to starve internal events, then internal events
never actually happen, signals don't get acked, etc)
