CFLOCK and session vars

["emadsen"]

I am building a multiuser site with session vars.  I understand the need for 
exclusive locking when writing session vars, but am a little confused when it 
comes to reading them.  I have the need to use certain session vars within SQL 
queries, etc.  I do need to use exclusive here as well, right?  Also, Is this 
bad?  <cflock scope='session' timeout='30' type='exclusive'> <cfset mySess = 
session /> </cflock>  I'd rather not have a hundred cflock statements within my 
CFC functions, etc.
