Subject: Some questions about Ruby 1.9

    I fear many of my questions will belong to the "often asked" category 
but a google search wasn't too fruitful so here I am...

    I did find some information on the state of threading but I wanted to 
clear some things up.  If Ruby 1.9 will use system threads, what will happen 
to the green threads?  What will happen to libraries that require green 
threads, like generator.rb?  Will they end up using system threads?
    If Ruby is using system threads, does that mean Ruby will be thread 
safe?  That is, will we be able to call into an embedded Ruby interpreter 
from multiple threads?

    Matz's most "regretting" behaviour of Ruby is that block variables are 
local to the block.  Will this be changed in Ruby 1.9?  If so, how will that 
affect threads, since they're made from blocks?  Will thread variables just 
leak right out into the defining scope?

    Finally, if Ruby will now be compiled into bytecode, will we be able to 
run the bytecode without the Ruby source?  Will Ruby be able to do this in 
an embedded application?

    These are what are on my mind, at the moment.  If I think of any others, 
I'll add them to this thread.
    Thank you...
