Speaking of stack groups, could someone on the list either talk about
or give some references to stack groups. I am interested in possible
performance comparisons on multiple processors to current thread
implementations like Solaris LWP or Digital Unix pthreads. Dual
pentium boxes are in the range of affordability now and I have been
thinking about getting on just to play with some of this stuff.
