[info-mcl] Trap timeline

[peter]

Looking at #_CGSetLocalEventsSuppressionInterval, I find that it is 
depreciated in 10.6 
<http://developer.apple.com/Mac/library/documentation/Carbon/Reference/QuartzEventServicesRef/DeprecationAppendix/AppendixADeprecatedAPI.html>, 
the replacement is CGEventSourceSetLocalEventsSuppressionInterval.

This brings to mind how we maintain traps to keep up with the 
evolution of the MacOS. Also where and how we document the current 
state of MCL traps.

Might it be useful if we had the ability to warn of obsolescence 
given our choice  to be compatible with a certain vintage of MacOS. 
I assume running (REINDEX-INTERFACES) is a bit irrelevant as it'd be 
as quick (and cleaner) to download a complete copy of the appropriate 
MCL.
