New Bound Threads Proposal

[Alastair Reid]

I haven't looked at the new proposal closely but I'm very disturbed when 
Wolfgang reports:

> *) It violates requirement #4 "The specification shouldn’t explicitly
> require lightweight “green” threads to exist."

> *) The blocking behaviour of foreign calls is specified with a bias
> towards GHC's implementation. [...]

If true this will make it harder to implement the proposal in Hugs and NHC.

Also, I think the experience of most language designs that I know of is that 
if your design reflects too much of your current implementation technique, 
then you're creating problems for yourself in the future.  (Examples: ML 
modules, C typedefs, most C++ features, ...)
