Code Issues Proposed changes

Fix races in conditionals tests

Browse Source 
In convergence, resources have a tendency to appear and disappear in their
own time, not atomically with a change to the stack state. Therefore when
testing conditionals (i.e. looking for resources to appear/disappear) we
must be careful to take into account the states of the resources we find to
avoid race conditions.
