Subject: timeout-driven heartbeat.
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=0f5a20828e553cddc69818a7e14e03665c113f05;p=openbsd

timeout-driven heartbeat.
right thing would be to pass beat count as an argument to timeout
routine (casted to (void *)) avoiding static counter, but
doing timeout_set() every timeout_add() sounds kinda uncool.
well, pondering in the struct timeout guts would be even more ugly.
