It sure is odd, but how is that semantics a problem when it comes to
thread switches? From a usability perspective it sure can be a problem
if several threads changes buffer local values and combine it with
dynamic bindings, but that's an application problem. I can't see any
inherent design problem keeping the odd behavior in a threaded
environment. Is it that the implementation of dynamically bound buffer
local values makes it difficult to fix context switching for them?
