I can't address the issue of whether or not "most" such projects require 
distributed locking, because I'm not familiar with more than half of 
such projects, as you appear to be. <wink>

On the other hand, I am (somewhat) familiar with Jeffrey's stated 
problem area (two postings of his earlier in the thread) and it really 
doesn't sound like he needs such a thing.  Would you normally expect to 
need distributed locking for a simple system where you had long-running 
computations and wanted to improve performance by using multiple CPUs?

Of course, only he can tell for sure.
