You have to be careful with developer feedback. Developers inexperienced
with pthread-style threads-and-locks typically like the model, since it's a
simple abstraction that *superficially* appears to map easily onto their
existing sequential code (e.g. because they can carry on using lots of
shared state). It's not until you get more experienced with it in a large
system that you really feel the pain, and appreciate why an apparently more
restrictive model might work better.
