This class of bugs can take many forms, and both of the major bugs that led to the DAO's collapse were bugs of this sort. The first version of this bug to be noticed involved functions that could be called repeatedly, before the first invocation of the function was finished. This may cause the different invocations of the function to interact in destructive ways.
