Bug description:SyncEvent fires only when someone is waiting

Description:
------------
Using package 'sync' PECL extension;

When an instance of SyncEvent calls fire() in a thread, the other
instance of SyncEvent just gets fired if it is executing wait(). If the
thread is processing other things, the next call to wait() will wait
indefinitely.

This bad behaviour was observed just on Linux with sync 1.1.0. On
Windows, sync 1.1.0 behaves correctly (the next call to wait() knows the
event was already fired). Sync 1.0.1 (the previous version) behaves
correctly on both platforms, Windows and Linux.

Test script:
---------------
// a single-threaded example:
$event = new SyncEvent("Test-123", true);
$event->fire();
if ($event->wait(0))
  echo "Fired, ok";
else
  echo "Not fired?";

Expected result:
----------------
On any platform, any version should have to print "Fired, ok".

Actual result:
--------------
On Windows, Sync 1.0.1 and 1.1.0 prints "Fired, ok".
On Linux, Sync 1.0.1 prints "Fired, ok", but Sync 1.1.0 prints "Not
fired?".
