Thread B->C will not wait, because CFLOCK is "ADVISORY" locking, meaning it is the
CFLOCK itself that causes the wait for the resource to be freed up. Cold Fusion takes
no automatic action for you (unless you turn on those options in the administrator).
It is up to the programmer to control resource locking with CFLOCKs.
So if you put a CFLOCK around a resource, and DONT put a CFLOCK around another use of
that same resource, the first lock was useless.
