When creating a timer/event handler reference counting is used. So it could be possible (in theory) that libxlDomainObjPrivateFree is called with reference counting >1. The problem is that libxlDomainObjPrivateFree leave the object in an invalid state with ctx freed (but still having dandling pointer). This can lead timer/event handler to core. This patch implements a dispose method for libxlDomainObjPrivate, and moves freeing the libxl ctx to the dispose method, ensuring the ctx is valid while the object's reference count is > 0.
