Subject: Get rid of SocketServer::checkTimeouts()
X-Git-Tag: v1.9.90~65^2
X-Git-Url: https://source.dussan.org/?a=commitdiff_plain;h=a4308c9;p=tigervnc.git

Get rid of SocketServer::checkTimeouts()

It doesn't belong on each socket server object as timers are global.
Force implementations to call the Timer system directly instead,
avoiding any middle men.
