Race condition in state/allclasses

[Chip Seraphine]

I've been having mysterious module failures on some of my hosts for a 
while, and I finally found out the cause.

My modules get their list of defined classes by parsing 
$(workdir)/state/allclasses.  Unfortunately, the contents of that file 
do not always reflect the actual classes of their parent cfagent 
process!  If the cfagent restarted a cfexecd or cfservd earlier in the 
run, then the resulting 'cfagent -z' child processes appear to stomp on 
the allclasses file, causing the module to pick up a very minimalist 
(and incorrect) set of classes.

Could we have the 'detection' flags that cfexecd and cfservd use 
suppress updating allclasses?  I can't think of any reason why they 
would be needed, and just slow down those 'quickie' variable-getting runs.
