Issue 6.4: Concurrency and Expression 
EvaluationStatus: open
Date split: 31 May

Categories: Expressions,

Submitter: Alex

Description: During discussion of Issue 6.*, someone expressed 
the concern of potential racing condition situation for 
<completionConditon>. Yes, there would be potential racing conditions. 
However, by thinking it deeper, racing condition actually apply to ALL 
expressions evaluation under a <flow>, whenever data underlying 
expressions are mutable. Racing-related expressions include any boolean 
condition (e.g. a <while> or if-then-else boolean condition). The more 
interesting case is transition conditions of control links, which actually can 
be used to emulate some of <completionCondition> functionality in some 
cases and face a similar racing condition problem.
