I agree with Hyman.  I once used the Booch component for a multitasking
application, but only in the package bodies because the multitasking
interaction needed to be specifically coded into the protected object.  I do
not think that built in task synchronization is all that helpful, but as
always there shouldn't be any nasty global effects in component libraries
that prevents two separately allocated data objects from being used at the
same time by different tasks.
