Dave,

Thats what I mean, best practice says use cfqueryparam, and every document
you read regardless of cfmx 5.0, 6.0, 7.0 says when writing to a variable
you will have a race condition.

Now I can't name the version I tested this on, but I followed one of the
articles directions on how a race condition will work. And you know what, it
proves that even this version of Coldfusion needs cflock around perstant
variable writes.

So I went back a version, and tried v7.02 on the same test, same thing the
results indicate a cflock is needed.

So your point is?
