[Buildbot-devel] locking and properties?

I need to limit the number of instances of builds from a set of  
builders that run at once ... a perfect situation for a counting lock  
at the builder level.  However, I only want to do this when a certain  
property is set.  I don't see how I can approach this... ideas?

(The reason for needing to do it only when the property is set is that  
the property enables a step in the various builders that can set up a  
deadlock condition... and limiting the number that run simultaneously  
avoids it.  I don't want to use the lock all the time because it hurts
