Dear Pythonauts,

    I usually lurk on the comp.lang.python newsgroup.  I'm not an expert
in the slightest, but I have had a growing feeling that there's
something definitely lacking in the concurrency aspects of Python.  It
is the same problem with Java.  Forgive me if I don't know the right
vocabulary, but Python concurrency seems to be exposed at too "low a
level".  It's like assembler:  it's all _possible_ to implement, but in
practise it's very complicated and fragile, glitchy, and really
difficult to extend.  Like programming in Dartmouth BASIC with just
conditionals and "goto" instructions, before structured programming.

    A higher-level system of concurrency, not based on monitors and
locks and great programmer discipline, will ultimately require making
"Python 3000" a reality.  

    In the meantime, is there anywhere, or any thing, that discusses the
various concurrency options related to Python?  There's Stackless Python
(which I can't make head or tail of; I have been unable to find any
lucid overview, or genuine explanation of the purpose of the design.)  I
know that there's a package for an Erlang system for Python, somewhere
("Parnassus" probably).  There's probably a Py-CSP somewhere too.  Lots
of trees, but where's the Wood?

    Where are concurrency/distributed models compared and discussed?

With kind regards,    

Sandy
