That is a pretty broad generalization.  Advisory locks are quite useful
when you are dealing with co-operative access, which happens automatically
if you've got multiple clients utilizing the same library code.
 
I think it would be unusual to have arbitrary clients accessing something like
a shared file (or shared socket...).
