sighandler_t is not UNIX. Regression from: 7f09126e068015db54c56bb982b8f91065375700 Signed-off-by: Jeremy Huddleston Sequoia <jeremyhu@apple.com> Reviewed-by: Peter Hutterer <peter.hutterer@who-t.net>
2012-08-07os: don't unconditionally unblock SIGIO in OsReleaseSignals()Peter Hutterer1-0/+36
Calling OsReleaseSignal() inside the signal handler releases SIGIO, causing the signal handler to be called again from within the handler. Practical use-case: when synaptics calls TimerSet in the signal handler, this causes the signals to be released, eventually hanging the server. Regression introduced in 08962951de.
