You don't need to lock MyQuery if you name it Request.MyQuery (that is,
give it Request scope).

A cached query is a cached query. You reference it by its name in your CF
templates, but CF includes, in addition, reference by SQL. So if by
"modifying the contents of a cached query" you mean you have a dynamic
query that's cached, for example:
<CFQUERY Name = "MyQuery"
SELECT * FROM MyTable WHERE ID = #FORM.ID#
then CF will cache a distinct dataset for each value of #FORM.ID#
OTOH, if by "modifying the contents of a cached query" you mean you modify
the data in the underlying database, my *guess* is that this does not
affect the cached query until it's requested after it times out.
