+Solaris FEN support in Gamin
+
+https://bugzilla.gnome.org/show_bug.cgi?id=730679
+http://osdyson.org/issues/172
+http://hg.osdyson.org/solaris-desktop-spec-files/raw-file/8f7c0cd200a9/patches/gamin-01-all.diff
+
+Fixed issues after the initial integration:
+1) Using freed node_t pointer in node_add function.
+Mitigation: When a node is removed, we also remove all the events in the
+event queue that contain a reference to this node to avoid future memory errors.
+2) A missing call to node_lstat before calling port_add function.
+When the system is under load, the timing of callbacks might cause that port_add is
+called on a node which access, change, and modification time was not read/updated.
+Mitigation: Call node_lstat before port_add in node_add_event function.
