It is recognised that such problems cannot be prevented in JCSP and
C++CSP.  However, occam is a practical implementation of CSP that does
provide safe encapsulation.

CSP scales up well if you can use the compositionality nicely.  However
how well you can do that depends on the design of your system.  No
system is a silver bullet, but that does not stop some being better
than others at given areas.
